Kadence Petersen · Answer 1

This is the concept of volumes of solid figures;

To calculate for the volume of material required we calculate for the volume of the pyramid;

volume of the pyramid is given by:

volume = (length*width*height) / 3

but in our case the base of the pyramid is square, therefore:

length=width=2 ft

height=6 ft

hence;

volume = (2*2*6) / 3

volume=8 ft^3

The answer is 8 ft^3

8ft cubed (d/4) is the correct answer
