Hey there, first you need to know the integers rules. So, how you can see a negative times a positive is negative. So -5 x 1 = -5. -5 x 11 = -55. -55 x 4 = -220
The volume for any cube is length x width x height, so in this case because all side of cube is the same, let it be y. y x y x y = 27 y = 3 so each side will be 3 inches
