3D Shapes and Nets Study Notes | Maths Learn & Test

There are a number of 3D shapes that you need to be familiar with.

In addition you need to know how to work out the volume of a Cuboid.

Volume is Length x Width x Height Volume = lhw

A Cube is a special case of a cuboid where Length = Width = Height

A Net is a 2 dimensional shape that can be folded to create a 3 dimensional shape. There are 4 basic nets that you should know.

Remember the Surface Area of Net = Surface Area of Solid

A cuboid has two sides that are 3cm and 5cm and its volume is 120cm³ Calculate its height.

Volume = Length x Width x Height So, 120 = 5 x 3 x h That makes h = 8cm
