First let’s work out the volume of the cube. A cube is different to other cuboids because all its dimensions are equal in length. However, you can still use the same formula to calculate the volume.

For an edge of length \(x\), the volume of a cube is given by the formula \(V\) = \(x\)³. To calculate the edge of a cube: Count the number of cm³ in the top layer. There are 16 unit cubes.
