The question is asking us to find the volume of the pyramid when base area and height is given.
The formula to find volume of pyramid is :
Volume of a pyramid = 1/3 base area x height
Given base area = 600 ft2
Height=88 ft.
Substituting the values of base area and height
Volume of Pyramid = 1/3 x 600 x 88
= 52800/3= 17600
Volume of pyramid= 17600 ft3
