Find the volume of material used to construct the Red Pyramid in Cairo, given that it has a height of 105m, a base length of 220m, and is estimated to be 96% solid
+248 I'm assuming the pyramid has a square base for this
The formula for the volume of a pyramid is 1/3*base area*height
base area=2202=48400m2
(if the area of the base is not square, use the side length to find the area of whatever shape it is and substitute it in)
height=105m
so the volume of the pyramid is 1/3*48400m2*105m=1,694,000m3
Except the pyramid is only 96% solid so the volume of material used is .96*1694000=1,626,240m3
