Find the surface area of a rectangular pyramid with these measurements: l =
8 yd., w = 4 yd., and h = 2 yd. (1 point)
• 43.31 yd.?
O 72.52 yd.2
• 66 yd.2
• 55.55 yd.2
To find the surface area of a rectangular pyramid, we use the formula:
Surface Area = (l*w) + 0.5*l*√(w/2)² + h²
Given:
l = 8 yd
w = 4 yd
h = 2 yd
Plugging the values into the formula:
Surface Area = (8*4) + 0.5*8*√(4/2) + 2²
Surface Area = 32 + 0.5*8*√(2) + 4
Surface Area = 32 + 0.5*8*1.414 + 4
Surface Area = 32 + 4 + 4
Surface Area = 40 + 4
Surface Area = 44
Therefore, the surface area of the rectangular pyramid is 44 square yards.
