Question

PLEASE HELP

Rock it out builds stage sets for rock concerts in the shape of a square pyramid. One set has a base that is 12 feet long and 12 feet wide. The slant height of the set is 13 feet. What is the surface area of the stage set?

Answer 1

I am pretty sure it's 312ft^2

Explanation:

If you do 12x13/2 its 78

then you would do 78 x 4

and you get 312

so its 312ft^2
