Today in maths, we are going to be learning how to find the volume of a shape.
The volume is the amount of space that a 3D shape takes up.
You can calculate the volume of a shape by multiplying the height x width x depth.
On the questions provided on the word document, you have been given the volume amount and you need to find out the missing length of the shape. In order to do this, you will need to do the inverse and work backwards.
If the volume of a cuboid = 660cm3
The length = 11cm
The width = 5cm
How would we work out the height of the shape?
Thinking back to our formular (volume = height x width x depth) we need to put those numbers in the calculation and then do the inverse.
660 = 11 x 5 x ?
11 x 5 = 55
660 divided by 55 = 12
Therefore, the height of the shape is 12cm.
Have a go at the questions on the word document below and see if you can work out the missing length to each shape.
You can either type your answers on the word document or you can write them in your book.
