Question

No cause really no one’s helping me D:

Answer 1

well, let's take a peek at the pyramid, hmmmm it has a triangular face that has a height of 5 and a base of 4, wait a second! it reallyi has 4 of those, ooook, and then it has a bottom that is a 4x4 square.

`\stackrel{\textit{\large Areas}}{\stackrel{four~triangles}{4\left[ \cfrac{1}{2}(4)(5) \right]}~~ +~~\stackrel{square}{(4\cdot 4)}}\implies 40+16\implies 56`
