Frank’ s Tank Frank won a magic goldfish at Math Fiesta last year. His goldfish was small, so he bought a cube-shaped fish tank with a volume of 1 ft3.

Frank’s goldfish grows every year, so every year he buys a tank that is one foot longer, wider, and taller than the year before. If Frank’s buys a new tank for 6 years, what will the dimensions of the 6th tank be?

Fill out the table below to find the appropriate dimensions.
