## SOLUTION This solution is FREE courtesy of BrainMass!

1. volume of cube = (side)^3 = 2.5^3 = 15.625 cubic cm

2. volume of sphere = (pi)(r^3)(4/3) = (pi)(5.2^3)(4/3) = 588.98 cubic inch

3. first, we find the cone's height. Given slant (20cm) and radius (12 cm), the height is the longer side of a right triangle. So height =sqrt (20^2 - 12^2) = 16

volume of cone = (1/3)(pi)(r^2)(h) = (1/3)(pi)(12^2)(16) = 2412.74 cubic centimeters
