The formula to find the surface area of a rectangular pyramid is given by:
Surface Area = lw + lh + wh
Given:
l = 8 yd.
w = 4 yd.
h = 2 yd.
Substituting the given values into the formula, we get:
Surface Area = (8 yd.)(4 yd.) + (8 yd.)(2 yd.) + (4 yd.)(2 yd.)
Surface Area = 32 yd² + 16 yd² + 8 yd²
Surface Area = 56 yd² + 8 yd²
Surface Area = 64 yd²
Therefore, the surface area of the rectangular pyramid is 64 yd².
Surface Area = lw + lh + wh
Given:
l = 8 yd.
w = 4 yd.
h = 2 yd.
Substituting the given values into the formula, we get:
Surface Area = (8 yd.)(4 yd.) + (8 yd.)(2 yd.) + (4 yd.)(2 yd.)
Surface Area = 32 yd² + 16 yd² + 8 yd²
Surface Area = 56 yd² + 8 yd²
Surface Area = 64 yd²
Therefore, the surface area of the rectangular pyramid is 64 yd².
