V=1/3 x area of the base x height
Ex.
you have a rectangular base of the pyramid and you need to get the area of that rectangle by multiplying the lenght and the width for example:
L=21m x W=8m=168m²=area of the base
then multiply it by the height of the pyramid like 26m
168 x 26=1456m³.
we use m³ for the final answer because it means cubed
1456meters cubed
