Volume of cuboids
Length × width × height — three measurements, one cubic answer.
A cuboid is a 3D solid with six rectangular faces (a box shape). To find the volume — the amount of space inside it — you multiply the three side lengths together:
Because you multiplied three lengths, your answer is in cubic units: , or .
A cube is just a cuboid with all three lengths equal, so where is the side length. A cube of side has volume .
If a question gives the volume and two of the three lengths, you can find the missing length by dividing: .
- Volume of a cuboid: V = l × w × h.
- A cube has V = a³ (all three lengths equal).
- Answer is in cubic units (cm³, m³).
- Find a missing length by dividing the volume by the two known lengths.
