Question

You are making poster board boundary markers in the shape of square pyramids for a relay race. If you are including an 8-inch square as the bottom and you want the slant height to be twenty-nine inches, how much poster board do you need?

five hundred twenty-eight square inches

five hundred seventy-six square inches

six hundred forty square inches

seven hundred sixty-eight square inches

Answer 1

A = 1/2bh
A=1/2(8)(29)
A = 116


(116)(4 triangles) = 464
SA = 464 + 64 = 528 = five hundred twenty - eight square inches.
