Can someone me with a practice question?
suppose a packaging company wants to create three types of boxes that are cubes and increase in size in a specific pattern: 1. the side lengths of the middle-sized cubes edges are 2 inches longer than those of the smallest cube. 2. the side length of the largest cubes edges are 2 inches longer than those of the middle-sized cube. 3. the sum of one side length of each of the three cubes equals y. 4. the volume of all three cubes combined is 24y.
write a system of equations based on the given information.

Large rectangles = 2 x 3 x 6
medium rectangles = 2 x 2 x 6
small rectangles = 2 x 2 x 3

surface area = large rectangles + medium rectangles + small rectangles = 36 + 24 + 12 = 72 cm^2
