The volume of the cone is equal to 1 of the volume of the cylinder, and the height of the cylinder is equal to the height of the cone (×).

The volume of cuboid, cube and cylinder can be calculated by V=sh (√).

If a cone and a cuboid have the same bottom surface and the same height, then the volume of the cone is equal to 1(√) of the cuboid volume.

The area at the bottom of the cylinder is enlarged by 2 times, and the height is reduced by 4 times (×) to keep its volume unchanged.
