Explain why the weight of an object is different on earth and the moon even though the object’s mass is the same in both places. 5. what formula do you use to determine the volume of a rectangular solid?

There is a thing called gravity. Gravity in the earth causes anything to stay down. There was an experiment a person held a plastic box with bricks on earth. It was really hard to pick it up. Then in the ISS (International Space Station) the same person help and it was so much easier no hardship at all, even a baby can do it!! 
5. Length times With times Hight = Volume or L*W*H=V

Weight depends on acceleration due to gravity and similarly acceleration due gravity depends on force of gravity. The force of gravity of the moon is 6 times less than on earth. As there is a difference in acceleration due to gravity between the earth and the moon, the magnitude of weight also vary. The mass is also independent of gravity, so it does not change anywhere. 
You use the formula: 
V = LWH

Ithink the answer is a or d.
