We had to build our own cuboid out of paper because there was no-more cardboard. It was a big experience at measuring and finding out how things can be equal.
This is a 2D cube the length is 14cm and the width id 4cm so if we multiply the 14cm and the 4 cm we will get 56cm2.
So if we multiply the width of the 3D shape, The length of the 3D shape and also the height of the 3D shape. So that will be 14cmx3cmx14cm = 588.
