A right circular cone is inside a cube. The base of the cone is inscribed in one face of the cube and its vertex in the opposite face.
Express the volume of the region between the cone and the cube in terms of s where s denotes the length of the edge of the cube.
:
We know: s^3 = vol of cube; also s = the height of the cube; .5s = the radius
therefore
1%2F3*pi%2A%28.5s%29%5E2+%2A+s the volume of the cube
which is
1%2F3*pi%2A.25s%5E2+%2A+s
1%2F3*pi%2A.25s%5E3
Cube vol - cone vol = region outside the cone, inside the cube
V = s%5E3 - (1%2F3*pi%2A.25s%5E3)
