Volume of cubes and cuboids:

We know that volume can be considered in terms of layers.

The volume is:
The number of cubes in 1 layer × The number of layers.

In the example on "Cubes and Volume" we saw that this shape has 12 squares per layer, and three layers.

Volume = 12 × 3 = 36

Just like for flat shapes, the lengths of the edges is related to the volume!!

The edges of the cuboid have a length 4cm, a width 3cm and a height 3cm.
The area of 1 layer = 12cm².
The volume = 36cm³.

The link? You multiply the length, width and height to get the volume!! So we can say:

The volume of a cuboid:
= length × width × height

Remember that for a cube, the length = the width = the height, so we can say:

Volume of a cube:
= length × length × length.
