To find the surface area of a rectangular pyramid, you need to calculate the area of each face and add them up.
The rectangular pyramid has:
- Length (l) = 8 yards
- Width (w) = 4 yards
- Height (h) = 2 yards
The surface area is given by:
Base area = l × w
= 8 yards × 4 yards
= 32 square yards
Face area = (l × h) / 2
= (8 yards × 2 yards) / 2
= 8 square yards
Therefore, the total surface area of the rectangular pyramid is:
32 square yards (base area) + 4×8 square yards (face area)
= 32 square yards + 32 square yards
= 64 square yards.
The closest answer to the calculated surface area is 66 yards^2.

use the formula for the surface area of a square pyramid to find the surface area if the base Edge length is 5 yd and the height is 25 yds. round to the nearest whole number
The formula for the surface area of a square pyramid is:
Surface Area = Base Area + (1/2) × Perimeter of Base × Slant Height
Given:
Base Edge Length (l) = 5 yd
Height (h) = 25 yd
First, let's calculate the base area:
Base Area = l^2
Base Area = 5 yd × 5 yd
Base Area = 25 yd^2
Next, we need to calculate the perimeter of the base:
Perimeter of Base = 4 × l
Perimeter of Base = 4 × 5 yd
Perimeter of Base = 20 yd
Now, we need to find the slant height, which can be found using the Pythagorean theorem:
Slant Height = √(l^2 + h^2)
Slant Height = √(5^2 + 25^2)
Slant Height = √(25 + 625)
Slant Height = √650
Slant Height ≈ 25.5 yd
Finally, we can calculate the surface area:
Surface Area = Base Area + (1/2) × Perimeter of Base × Slant Height
Surface Area = 25 yd^2 + (1/2) × 20 yd × 25.5 yd
Surface Area = 25 yd^2 + (1/2) × 510 yd^2
Surface Area = 25 yd^2 + 255 yd^2
Surface Area = 280 yd^2
Therefore, the surface area of the square pyramid is approximately 280 yd^2 when rounded to the nearest whole number.
Surface Area = Base Area + (1/2) × Perimeter of Base × Slant Height
Given:
Base Edge Length (l) = 5 yd
Height (h) = 25 yd
First, let's calculate the base area:
Base Area = l^2
Base Area = 5 yd × 5 yd
Base Area = 25 yd^2
Next, we need to calculate the perimeter of the base:
Perimeter of Base = 4 × l
Perimeter of Base = 4 × 5 yd
Perimeter of Base = 20 yd
Now, we need to find the slant height, which can be found using the Pythagorean theorem:
Slant Height = √(l^2 + h^2)
Slant Height = √(5^2 + 25^2)
Slant Height = √(25 + 625)
Slant Height = √650
Slant Height ≈ 25.5 yd
Finally, we can calculate the surface area:
Surface Area = Base Area + (1/2) × Perimeter of Base × Slant Height
Surface Area = 25 yd^2 + (1/2) × 20 yd × 25.5 yd
Surface Area = 25 yd^2 + (1/2) × 510 yd^2
Surface Area = 25 yd^2 + 255 yd^2
Surface Area = 280 yd^2
Therefore, the surface area of the square pyramid is approximately 280 yd^2 when rounded to the nearest whole number.

To find the surface area of a square pyramid, you need the base edge length (l) and the slant height (s).
Given:
Base Edge Length (l) = 8 ft
Slant Height (s) = 16 ft
First, let's calculate the base area:
Base Area = l^2
Base Area = 8 ft × 8 ft
Base Area = 64 ft^2
Next, we need to calculate the lateral area, which is the summed area of the four triangular faces:
Lateral Area = 4 × (1/2) × l × s
Lateral Area = 4 × (1/2) × 8 ft × 16 ft
Lateral Area = 128 ft^2
Finally, we can calculate the surface area by adding the base area and the lateral area:
Surface Area = Base Area + Lateral Area
Surface Area = 64 ft^2 + 128 ft^2
Surface Area = 192 ft^2
Therefore, the surface area of the square pyramid is 192 square feet. None of the provided options (128 ft, 320 ft, 512 ft, 256 ft) match the calculated surface area.
