A frustum of height 4 is part of a larger pyramid of height 6. The larger pyramid is composed of the frustum and a smaller pyramid...?
If the volume of the smaller pyramid is 210, what is the volume of the frustum?
If the volume of the smaller pyramid is 210, what is the volume of the frustum?

The small pyramid has a height of 2; the large pyramid has a height of 6.
The volumes are proportional to the cube of their heights.
small / large = 2^3 / 6^3 = 210 / x
1 / 27 = 210 / x
x = (210)(27) = 5670 cubic units
