Question from charlotta, a parent:

My son needs to find the 3 dimensions of a toy chest that has to have a volume of 24 cubic feet can you show how to get the answer

Hi Charlotta,

The length, width and height of the toy chest can be any three numbers as long as

length × width × height = 24.

Ask your son if he can tell you three numbers that when multiplied together give 24. If he doesn't have an answer ask for two numbers that when multiplied together give 24. Then take the larger of the two numbers he gives you and ask the same question, what two numbers when multiplied together give this number.

I hope this helps,
