75

Answer 2

@phi Completely confused

Answer 3

the volum of a pyramid you can calcule using formula

V = area of base *height /3

then volum A = 9*9*4 /3 = 3*9*4 = 108 in^3

then now just divide the volum of B by volum of A

Answer 4

They want you to figure out the volume of pyramid A

Pyramid A is a square pyramid with a base side length of 9 inches and a height of 4 inches.

volume is area of base * height then divide by 3

the base is a square with side = 9. area of a square is side * side
can you do that ?

Answer 5

Is the answer 75?
