The base of the pyramid doesn't have to be regular for the formula to apply.
V = 80 cm3
Find the volume of the triangular pyramid.
The B in the volume formula represents the area of the base, which is a triangle in our case.
V = 80 in2
We're vacationing in Egypt and we come across the Pyramid of Giza. Its square base has an edge of 756 feet and it's 453 feet high. If it were filled to the brim with nothing but mummies, how creepy would that be? Answer: A lot. How many mummies would it hold? Assume a mummy takes up about 12 cubic feet of space.
Find the volume of the pyramid. Then convert cubic feet to mummies. That's a weird sentence.
The pyramid would have a volume of 86,301,936 ft3 and contain more or less 7,191,828 mummies. Suddenly, a mummy apocalypse seems far more likely than a zombie one.
