Question

HELP PLEASE!)

A square pyramid has surface that is covered in dark glass. The sides of the pyramid are 456 feet in length. The slant height of the pyramid is 185 feet.

Find the lateral surface area to determine the square feet of glass needed to cover the surface of the pyramid.

Answer choices
376,656 ft^2
42,180 ft^2
337,440 ft ^2
168,720 ft^2

Answer 1

it should be 376,656 ft^2 bc
1. square the bases (456 x 456 = 207936)
2. four triangles 4(1/2 x base x height) which would be 4(1/2 x 456 x 185) = 168720
then add up 168720 + 207936 = 376656
hope this helps :D
