  • How to calculate the volume of cuboids and compound shapes


Volume1
Volume?

The space a 3D shape takes up

tells you how much a container will hold


Volume of a cuboid

Depends on

How long it is

h

How wide it is

b

How high it is

l

Volume = length X breadth X height

v = lbh


5cm

4cm

10cm

v = lbh

= 10 X 4 X 5

= 200cm3

= 200ml

remember 1000ml = 1 litre
