To find the surface area of a rectangular pyramid, we need to calculate the areas of the triangular faces and the rectangular base.
The area of each triangular face can be calculated using the formula A = 1/2 * base * height, where the base is the length of the rectangle and the height is the height of the pyramid.
Area of triangular face = 1/2 * 10 m * 15 m = 75 m^2
Since there are 4 triangular faces, the total area of the triangular faces is 4 * 75 m^2 = 300 m^2.
The area of the rectangular base can be calculated by multiplying the length and width of the base.
Area of rectangular base = 14 m * 10 m = 140 m^2.
Finally, we can find the surface area by adding the areas of the triangular faces and the rectangular base.
Surface area = 300 m^2 + 140 m^2 = 440 m^2.
Rounded to the nearest hundredth, the surface area of the rectangular pyramid is approximately 440.00 m^2.
None of the given answer choices match the calculated surface area.
Find the surface area of rectangular pyramid with these measurements.
L = 14 m, w = 10 m, and h = 15 m
Round your answer to the nearest hundredth. (Keep in mind you have the height, not the slant height.)
