An aquarium in the shape of a rectangular prism has a bottom, no top, two square sides, and two sides the same height as the square sides but twice their length. The total area of the five sides is 1,568 in2. Find the volume of the aquarium. Complete the explanation of your reasoning.

Let x represent the length and height of the square sides. Then the longer sides and the bottom measure 2x by x. The total area of the five sides, in terms of x, is A = So, the total area of the five sides, A, is 1,568 in2. Solving for x we get x = .The tank's volume is in3.
