A cube has six sides. The area of each side in this case is what? The total area is what?
What is the cube root of 15?
Can the area of a circle be made equivalent to the area of a square? The volume of a cone is 1/3*pi*r^2*h. The volume of a square "cone", a pyramid, is 1/3*b^2*h. Can b^2 be made to equal pi*r^2? (hint: I disagree with Illusen)
The formula for the volume of a sphere is V = 4/3*pi*r^3
(I also disagree with Illusen here)
