Answer:Multiply the base area times the height to find the volume, which is the amount of packing material required
Step-by-step explanation: example :An empty box is shaped like a rectangular prism. The box has a base area of `9/10` square foot and a height of `1/3` foot. How much packing material is required to fill the box?
First, multiply the numerators, or the top numbers. 9 * 1 = 9
Then, multiply the denominators, or the bottom numbers. 10 * 3 = 30
So, the amount of packing material required is 9/30 cubic feet.
