Volume, surface area and nets of 3D shapes

Pick a solid, set its dimensions and get its volume and surface area with the formula. Slide a cutting plane through it to see the cross-section, and unfold its net.

Questions students ask

What is the volume of a cone?

V = ⅓πr²h, a third of the cylinder with the same base and height.

What is a net of a solid?

The flat shape you get when you unfold its surface; folding it back up makes the solid. Its area is the solid's surface area.
