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

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=220^{2}=48400m^{2}

^{(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*48400m^{2}*105m=1,694,000m^{3}

Except the pyramid is only 96% solid so the volume of material used is .96*1694000=1,626,240m^{3}
