To solve this problem, we will subtract the volume of the cylinder from the volume of the rectangular prism.

The volume of a cylinder is: pi*r^2*h
Substitute 2 in for r and 6 in for h. If the diameter is 4, then the radius is 2.
pi*2^2*6
pi*4*6
pi*24
=75.4 ft^2

The volume of the rectangular prism is: l*w*h.
Substitute 6 in for l, w and h, since all edges are equal.
6*6*6
36*6
=216 ft^2

Subtract 75.4 from 216
216-75.4=140.6

There is 140.6 cubic feet of concrete left in the block.
