1
Q
When do you use squared units e.g. centimetres
squared ( cm^2 ) or metres squared ( m^2 )?
A
When you are working out an area (or when the formula begins “A =”)
2
Q
When do you use cubed units e.g. metres cubed (m^3) or centimetres cubed (cm^3)?
A
When you are working out a volume (or when the formula begins “V =”)

A
“Length times Breadth”
or A = l x b
4

A
“Half Base times Height”
or A = b x h / 2
5
Q
How do you find the volume of a cuboid?
A
