The question
Question: find the volume of a box 4 long, 3 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 = 4, width = 3 and height = 2.
V = 4 × 3 × 2
4 times 3 is 12.
That is one layer of 12 cubes.
There are 2 layers.
So V = 12 × 2.
V = 12 × 2
12 times 2 is 24.
So the volume is 24 cubic units.
V = 24
Answer
V = 24
