Question from Dawn:

I need to purchase an item that is .4 cubic feet in size and the amount
I need is 5.625 cubic feet. How many bags do I need?


If the bags were 2 cubic feet in size and you needed 10 cubic feet then you would need 5 bags since 10 ÷ 2 = 5. You apply the same technique here, 5.625 ÷ 0.4 = 14.0625. Hence you need slightly more than 14 bags.
