Below are the most common 3D shapes you will come across and with 3D shapes, you need to be able to work out the volume of these shapes. In a number of cases, it is about recognising the ‘face‘ of the 3D shape and then multiplying the area of the face by the depth /or length of the 3D shape. If the 3D shape does not have a ‘face’ then you need to know the exact volume formula of the 3D shape
