Problem: Fish Tank Teaser Grade Level: 5th Grade Envisions Connection: Chapter 10 Content Standards: 5.MD.5.b Apply the formulas V =1 xwxh and V = 5 x h for rectangular prisms to find volumes of right rectangular prisms with whole-number edge lengths in the context of solving seal world and mathematic problems. Part1: Anna loves fish and has a rectangular prism shaped tank in her room. She keeps the tank in her room against a wall that is only 6 feet long. The tank is also 6 feet long, so it takes up the entire length of Anna's wall. Her tank is 3 feet tall and 2 feet wide. Find the volume of Anna's tank below. Show all of you work.

Part 2: Today Anna's cousin dropped off some new fish. She now needs a tank that has a volume three times greater than her old tank so the new fish have enough space to swim. She cannot buy a longer tank because it will not fit against the wall. Design a tank for Anna that has three times the volume of her old tank but still fits against her 6 foot long wall. Show all of your work. If you can, design more than one tank that will solve Anna's problem!​
