Example Using Surface Area and Volume to Solve Real-World Problems
The two cereal boxes have the shape of rectangular prisms. The company cares about its customers, so it wants the box to hold as much cereal as possible. The company also wants to help save the environment, so it wants to use the least amount of cardboard possible. Which box should the company choose to make? Explain.
To find out how much cereal each box holds and how much material is needed to make each box, you will need to find the volume and surface area of each box.
The boxes are each rectangular prisms. Use the formula V = Bh.
