To find the surface area of a rectangular pyramid, we need to calculate the area of the base and the area of each triangular face.
The area of the base is l*w = 8 yd. * 4 yd. = 32 yd.^2.
The area of each triangular face is 1/2 * base * height, where the base is the length of the pyramid and the height is the height of the pyramid.
The area of each triangular face is 1/2 * 8 yd. * 2 yd. = 8 yd.^2.
Since a rectangular pyramid has 4 triangular faces, the total area of the triangular faces is 4 * 8 yd.^2 = 32 yd.^2.
To find the surface area, we need to sum the area of the base and the area of the triangular faces:
Surface area = base area + triangular faces area
Surface area = 32 yd.^2 + 32 yd.^2
Surface area = 64 yd.^2
Therefore, the surface area of the rectangular pyramid is 64 yd.^2.
The closest available option is 66 yd.^2.
Find the surface area of a rectangular pyramid with these measurements: l = 8 yd., w = 4 yd., and h = 2 yd.(1 point) Responses 43.31 yd.2 43.31 yd. 2 66 yd.2 66 yd. 2 55.55 yd.2 55.55 yd. 2 72.52 yd.2
