She arranges the small cubes inside the shoebox in a way that they are stacked neatly in rows and columns. Once she cannot fit any more cubes, she counts the number of cubes. Then she multiplies the volume of one cube by the number of cubes she was able to fit in the shoebox. The product is the approximate volume of the shoebox,.
Deandre = x Kala = x + 6 Eric = 3(x+6) x + x + 6 + 3(x+6) = 119 2x + 6 + 3x + 18 = 119 5x + 24 = 119 5x = 95, x = 19 Deandre has $19 Kala has 19 + 6 = $25 Eric has 3(25) = $75
