To find the surface area of a right rectangular pyramid, we can use the formula:

Surface Area = base area + (0.5 x perimeter of base x slant height)

First, we need to find the base area:
Base Area = l x w
Base Area = 13 x 5
Base Area = 65 square units

Next, we need to find the perimeter of the base:
Perimeter = 2(l + w)
Perimeter = 2(13 + 5)
Perimeter = 2(18)
Perimeter = 36 units

Now, we need to find the slant height. In a right rectangular pyramid, the slant height can be found using the Pythagorean theorem:

l^2 + w^2 = h^2
13^2 + 5^2 = h^2
169 + 25 = h^2
194 = h^2
√194 ≈ 13.928 units

Now, we can plug these values into the formula to find the surface area:
Surface Area = 65 + (0.5 x 36 x 13.928)
Surface Area = 65 + (0.5 x 36 x 13.928)
Surface Area = 65 + (0.5 x 501.408)
Surface Area = 65 + 250.704
Surface Area = 315.704

Therefore, the surface area of the right rectangular pyramid is approximately 315.704 square units.

To find the surface area of a right square pyramid, we can use the formula:

Surface Area = base area + (0.5 x perimeter of base x slant height)

First, we need to find the base area:
A square pyramid has a square base, so the base area is the side length squared.
Base Area = X^2
Base Area = 7^2
Base Area = 49 square units

Next, we need to find the perimeter of the base:
Since it's a square, the perimeter of the base is 4 times the side length.
Perimeter = 4X
Perimeter = 4(7)
Perimeter = 28 units

Now, we need to find the slant height. In a right square pyramid, the slant height can be found using the Pythagorean theorem:

(0.5*base perimeter) ^ 2 + height^2 = slant height^2
(0.5*28)^2 + Y^2 = slant height^2
14^2 + 10^2 = slant height^2
196 + 100 = slant height^2
296 = slant height^2
slant height ≈ 17.2 units

Now, we can plug these values into the formula to find the surface area:
Surface Area = 49 + (0.5 x 28 x 17.2)
Surface Area = 49 + (0.5 x 478.4)
Surface Area = 49 + 239.2
Surface Area = 288.2

Therefore, the surface area of the right square pyramid is approximately 288.2 square units.

To find the total area of the porch, we need to calculate the individual areas of the wooden triangle and the concrete square, and then add them together.

First, let's calculate the area of the wooden triangle. The area of a triangle can be calculated using the formula:

Area of a triangle = 0.5 x base x height

In this case, the base of the wooden triangle is b = 24 ft and the height can be calculated using the Pythagorean theorem:
height^2 = c^2 - b^2
height^2 = 30^2 - 24^2
height^2 = 900 - 576
height^2 = 324
height = √324
height = 18 ft

Now we can calculate the area of the wooden triangle:
Area of wooden triangle = 0.5 x 24 x 18
Area of wooden triangle = 0.5 x 432
Area of wooden triangle = 216 sq ft

Next, let's calculate the area of the concrete square. The area of a square is calculated as:

Area of a square = side^2

For the concrete part, the side length is a = 18 ft:
Area of concrete square = 18^2
Area of concrete square = 324 sq ft

Finally, we can find the total area of the porch by adding the areas of the wooden triangle and the concrete square:
Total area = Area of wooden triangle + Area of concrete square
Total area = 216 + 324
Total area = 540 sq ft

Therefore, the total area of the porch, considering the wooden part as a right triangle and the concrete part as a square, is 540 square feet.

To find the total area of the porch, we need to calculate the area of both the wooden part and the concrete part and then add them together.

Given:
a = 18 ft
b = 24 ft
c = 30 ft

First, let's calculate the area of the wooden part, which is a right triangle.

The area of a triangle can be calculated using the formula:
Area = 0.5 * base * height

In a right triangle, the base and height are given by a and b:
Area of wooden part = 0.5 * 18 * 24
Area of wooden part = 0.5 * 432
Area of wooden part = 216 sq ft

Next, let's calculate the area of the concrete part, which is a square.

The area of a square is calculated as:
Area = side^2

For the concrete part, the side length is given by a:
Area of concrete part = 18^2
Area of concrete part = 324 sq ft

Now, we can find the total area of the porch:
Total area = Area of wooden part + Area of concrete part
Total area = 216 + 324
Total area = 540 sq ft

Therefore, the total area of the porch, assuming the wooden part is a right triangle and the concrete part is a square, is 540 square feet.

To find the area of the object, we need more information about the shape of the object described by the dimensions X, Y, W, and Z.

If the object is a rectangular solid, which has six faces and all opposite faces have the same area, then the total surface area of the object is given by:

Total Surface Area = 2*(X*Y + X*W + Y*Z)

Now we can calculate the total surface area using the given dimensions:
Total Surface Area = 2*(3*10 + 3*4 + 10*5)
Total Surface Area = 2*(30 + 12 + 50)
Total Surface Area = 2*(92)
Total Surface Area = 184 square inches

Therefore, the total area of the object is 184 square inches.
