Hint: what's the formula for the volume of a pyramid? (you don't really need it, but it makes things easier)

Area of the base * Height * 1/3

OK, so what are the volumes of the two pyramids: the original and the new one?

barrycarter · Answer

OK, let's say the base of the smaller pyramid is a square with side length 's'. Now, what is the volume in terms of 's'?

anonymous97 · Answer

idk but the bigger pyramid has a height of 60 inches

barrycarter · Answer

OK, good. If the smaller pyramid's base has a side length of s, it's a square with side s. A square with side 's' has what area?
