Use the image to answer the question.

An illustration shows a pyramid with a rectangular base. The length of the base is 8 millimeters and the width 10 millimeters. The perpendicular heights from the apex to the base length is 12 millimeters and to the base width is 15 millimeters. The perpendicular heights are denoted by two right angle symbols on two of the lateral faces from the apex to the base by dashed lines.

To find the surface area of a rectangular pyramid, you need to calculate the sum of the areas of all its faces. The surface area of a rectangular pyramid is calculated using the formula:

Surface Area = (base area) + 1/2 * (perimeter of base) * slant height

where the base area is the area of the rectangle at the base of the pyramid, the perimeter of the base is the perimeter of the rectangle, and the slant height is the height of one of the triangular faces.

Without specific dimensions, it is not possible to calculate the surface area of the rectangular pyramid. You would need to know the base dimensions, the height of the pyramid, and the slant height of the triangular faces in order to calculate the surface area.

To find the surface area of the rectangular pyramid in this case, we will use the formula:

Surface Area = (base area) + 1/2 * (perimeter of base) * slant height

Given that the base of the rectangular pyramid has a length of 8 mm and a width of 10 mm, the base area can be calculated as:

Base Area = length * width
Base Area = 8 mm * 10 mm
Base Area = 80 mm^2

Next, we need to calculate the perimeter of the base. Since the base is a rectangle, the perimeter can be found by adding the lengths of all four sides:

Perimeter of Base = 2 * (length + width)
Perimeter of Base = 2 * (8 mm + 10 mm)
Perimeter of Base = 2 * 18 mm
Perimeter of Base = 36 mm

Now, we need to calculate the slant height. The slant height can be found using the Pythagorean theorem in each triangle formed by the height, the slant height, and half of the base:

Slant Height 1 = √( (height)^2 + (1/2 * length)^2 )
Slant Height 1 = √( 12^2 + 4^2 )
Slant Height 1 = √( 144 + 16 )
Slant Height 1 = √160
Slant Height 1 ≈ 12.65 mm

Slant Height 2 = √( (height)^2 + (1/2 * width)^2 )
Slant Height 2 = √( 15^2 + 5^2 )
Slant Height 2 = √( 225 + 25 )
Slant Height 2 = √250
Slant Height 2 ≈ 15.81 mm

Now, we can calculate the surface area:

Surface Area = Base Area + 1/2 * Perimeter of Base * (Slant Height 1 + Slant Height 2)
Surface Area = 80 mm^2 + 1/2 * 36 mm * (12.65 mm + 15.81 mm)
Surface Area = 80 mm^2 + 1/2 * 36 mm * 28.46 mm
Surface Area = 80 mm^2 + 18 mm * 28.46 mm
Surface Area = 80 mm^2 + 509.28 mm^2
Surface Area ≈ 589.28 mm^2

Therefore, the surface area of the rectangular pyramid is approximately 589.28 mm^2.

I apologize for the mistake. Let's correct the calculation:

The base area of the rectangular pyramid is:
Base Area = Length * Width
Base Area = 8 mm * 10 mm
Base Area = 80 mm^2

Next, we calculate the lateral surface area:
In a rectangular pyramid, each triangular face has an area of 0.5 * base length * slant height.

The slant height for the face with height 12 mm is the hypotenuse of a right triangle with sides 8 mm and 12 mm.
Slant Height 1 = √(8^2 + 12^2) = √(64 + 144) = √208 ≈ 14.42 mm

The slant height for the face with height 15 mm is the hypotenuse of a right triangle with sides 10 mm and 15 mm.
Slant Height 2 = √(10^2 + 15^2) = √(100 + 225) = √325 ≈ 18.03 mm

Calculate the lateral surface area for each face and sum them:
Lateral Surface Area = 0.5 * (Length * Slant Height 1 + Width * Slant Height 2)
Lateral Surface Area = 0.5 * (8 mm * 14.42 mm + 10 mm * 18.03 mm)
Lateral Surface Area = 0.5 * (115.36 mm^2 + 180.3 mm^2)
Lateral Surface Area = 0.5 * 295.66 mm^2
Lateral Surface Area = 147.83 mm^2

Finally, calculate the total surface area by adding the base area and the lateral surface area:
Surface Area = Base Area + Lateral Surface Area
Surface Area = 80 mm^2 + 147.83 mm^2
Surface Area = 227.83 mm^2

Therefore, the correct surface area of the rectangular pyramid is approximately 227.83 mm^2. Thank you for pointing out the error.

I apologize for the oversight. Let's correct the calculation:

Given:
Base Length = 8 mm
Base Width = 10 mm
Height to Length = 12 mm
Height to Width = 15 mm

1. Calculate the base area:
Base Area = Base Length * Base Width
Base Area = 8 mm * 10 mm
Base Area = 80 mm^2

2. Calculate the slant height for the triangular faces using the Pythagorean theorem:
Slant Height for Length = √(12^2 + (8/2)^2)
Slant Height for Length = √(144 + 16)
Slant Height for Length = √160
Slant Height for Length ≈ 12.65 mm

Slant Height for Width = √(15^2 + (10/2)^2)
Slant Height for Width = √(225 + 25)
Slant Height for Width = √250
Slant Height for Width ≈ 15.81 mm

3. Calculate the lateral surface area for the pyramid:
Lateral Surface Area = 0.5 * Base Perimeter * Slant Height for Length + 0.5 * Base Perimeter * Slant Height for Width
Base Perimeter = 2 * (Base Length + Base Width) = 2 * (8 mm + 10 mm) = 2 * 18 mm = 36 mm

Lateral Surface Area = 0.5 * 36 mm * 12.65 mm + 0.5 * 36 mm * 15.81 mm
Lateral Surface Area = 0.5 * 455.4 mm^2 + 0.5 * 568.68 mm^2
Lateral Surface Area = 227.7 mm^2 + 284.34 mm^2
Lateral Surface Area ≈ 512.04 mm^2

4. Calculate the total surface area:
Total Surface Area = Base Area + Lateral Surface Area
Total Surface Area = 80 mm^2 + 512.04 mm^2
Total Surface Area = 592.04 mm^2

Therefore, the correct surface area of the rectangular pyramid is approximately 592.04 mm^2. I hope this helps. Thank you for your patience.

I apologize for the previous errors. Let's try to get the correct answer using the correct calculations:

Given:
Base Length = 8 mm
Base Width = 10 mm
Height to Length = 12 mm
Height to Width = 15 mm

1. Calculate the base area:
Base Area = Base Length * Base Width
Base Area = 8 mm * 10 mm
Base Area = 80 mm^2

2. Calculate the lateral surface area for the pyramid:
Lateral Surface Area = 0.5 * Perimeter of Base * Slant Height 1 + 0.5 * Perimeter of Base * Slant Height 2

Calculate the slant heights:
Slant Height 1 = √(12^2 + (8/2)^2) = √(144 + 16) = √160 ≈ 12.65 mm
Slant Height 2 = √(15^2 + (10/2)^2) = √(225 + 25) = √250 ≈ 15.81 mm

Calculate the perimeter of the base:
Perimeter of Base = 2 * (Base Length + Base Width)
Perimeter of Base = 2 * (8 mm + 10 mm) = 2 * 18 mm = 36 mm

Lateral Surface Area = 0.5 * 36 mm * 12.65 mm + 0.5 * 36 mm * 15.81 mm
Lateral Surface Area = 0.5 * 455.4 mm^2 + 0.5 * 568.68 mm^2
Lateral Surface Area = 227.7 mm^2 + 284.34 mm^2
Lateral Surface Area ≈ 512.04 mm^2

3. Calculate the total surface area:
Total Surface Area = Base Area + Lateral Surface Area
Total Surface Area = 80 mm^2 + 512.04 mm^2
Total Surface Area = 592.04 mm^2

Therefore, the correct surface area of the rectangular pyramid is approximately 592.04 mm^2. Thank you for your patience.
