A planting box is made of two sizes of rectangular prisms. One type of prism measures 3" by 6" by 14". The other type measures 15" by 5" by 10". What is the total volume of three such boxes?
If you find the volume of the first one it would be 252. Then find the volume of the second one 750. When you add them together you get 1002. I hope this helps. :)
