The question

Question: find the volume of a box 7 long, 4 wide and 2 high.

1 Length × width × height

Volume is how much space is inside.

We count the 1 by 1 by 1 cubes that fit.

The volume of a box is V = length × width × height.

V = length × width × height

Now put the numbers in: length = 7, width = 4 and height = 2.

V = 7 × 4 × 2

7 times 4 is 28.

That is one layer of 28 cubes.

There are 2 layers.

So V = 28 × 2.

V = 28 × 2

28 times 2 is 56.

So the volume is 56 cubic units.

V = 56
Answer
V = 56
