Blocks in a box
You learn to work out how many blocks fit in a box.
How to work it out
- Work out how many blocks fit along the length, the width and the height.
- Multiply those three numbers.
- With 1 cm³ cubes, that is exactly the volume.
A box is 6 cm long, 4 cm wide and 2 cm high. A block is 2 × 2 × 1 cm. How many blocks fit inside?
- Work it out for each direction.
- Along the length 6 ÷ 2 = 3 blocks fit, along the width 4 ÷ 2 = 2, and up the height 2 ÷ 1 = 2.
- Multiply those three numbers: 3 × 2 × 2 = 12 blocks.
