How to use the Volume & Surface Area Calculator

  1. Choose the shape.
  2. Enter its dimensions.
  3. Read the volume, total surface area and lateral area.

What does this tool do?

Volume is the space a solid occupies; surface area is the total area of its outside. Both come up in packaging, construction, cooking and school geometry.

If your dimensions are in centimetres, the volume is in cm³ (1,000 cm³ = 1 litre) and the surface area in cm².

Why use it?

  • Seven common solids.
  • Lateral and total surface area.
  • Formulas shown.

The formula

Cylinder: V = πr²h, SA = 2πrh + 2πr²
Sphere: V = 4⁄3 πr³, SA = 4πr²
Cone: V = ⅓ πr²h, SA = πrl + πr²
