# Teacher Graded Assignment

One of the puzzle cubes will have a side length of 4 centimeters, and the size of the other is yet to be determined. A. Write an expression to represent the total volume of two different sized puzzle cubes as a sum of cubes, using m centimeters as the side lengths of the second puzzle. Ana + 4’3 (m + 4) (RNA – mm + 4) (m + 5) Calculate the total volume of the two puzzle cubes if m = 5 centimeters. (m + 4) (AMA – mm + 4) (m + 5) = 21 O KEY Inc. 3. A pet supply store is planning to offer cube-shaped fish tanks.

The store manager decides to order one tank with a 12-inch side length but has not yet decided on the size of the other. A. Write an expression to represent the total volume of two different sized tanks as a sum of cubes, using at centimeters as the length of the sides in the second tank. (12)AAA + (at)AAA = data + 1730 cry-Ana (at+ (2 x 7 -at+ AAA) Calculate the total volume of the two fish tanks fit = 7 inches.

Write a sentence to describe what the cubes represent and then write an expression to represent the total volume of the two items as a sum of cubes, using AAA to represent the side lengths in one cube and b to represent the side lengths in the other cube. At the grocery store there is a square box of live lobsters being ordered. Two sides are 5 and the others are yet to be determined. (92 + XA) = (93 + XX) Choose two different values for a and b and use these values to calculate a specific total volume for the two items. Ex.+x-xix
