3. Volume of a cuboid height, h length, l width, w
We can find the volume of a cuboid by multiplying the area of the base by the height.
The area of the base
= length × width
So,
height, h
Volume of a cuboid
= length × width × height
= lwh
length, l
width, w

4. Volume of a cuboid What is the volume of this cuboid? Volume of cuboid
= length × width × height
5 cm
= 13 × 8 × 5
8 cm
