Let us assume the volume of box B = x Now, the formula that needs to be followed is (scale factor)^3 = Volume of Box A/volume of Box B (1/5)^3 = 12/x 1/125 = 12/x x = 12 * 125 = 1500 m^3 So, from the above deduction, we can conclude that the option that is correct is the third option. I hope the answer helps you.
