Jamila last is building a square sandbox with 7 feet long she wants to put sand 2 feet deep in the box. how much sand should jamilla ordr

To find the answer you need to find the volume and would want to think of the sandbox as a rectangular prism and identify the length, width, and height. For this equation the height would be 2 feet because she wants it to be 2 feet deep. For the length and width both the values would be 7 feet because the base is a square. 

Using the equation Volume=Width*Height*Length. Then, plug the values into the equation to get V=7*2*7 which leaves you with V=98 feet^3. This means Jamila would need 98 feet^3 of sand to fill the sandbox.

This law is sometimes called the grouping property. as you can see, regardless of how the numbers are grouped, the answer is still 13. the associative law of multiplication is similar to the same law for addition. it says that no matter how you group numbers you are multiplying together, you will get the same answer.
