1. the sandbox you built has a measurement of 10ft in length, 5ft in width, and 2ft in height. using the formula for a rectangular prism, what is the volume in cubic feet?

2. now that you know the volume of the sandbox, how many sandbags will you need to fill the sandbox if each bag is half a cubic foot (.5 cubic feet)?

3. if each bag is 50lbs, how many lbs of sand did you use to fill the sandbox?
