Miguel used a balance to compare the masses of two boxes that are the exact same size and weight when empty. When he placed a box on each side of the balance, it tipped on one side. Which of the following would explain why this happened? Since the boxes have the same size and weight, the boxes need to be placed on the scale at the same time to balance it.
The boxes have different masses because they have different objects inside them, meaning one has more matter.
The cardboard is thinner on one of the boxes, making its mass greater than the mass of the other box.
The scale must be broken since the boxes have the same size and weight, the mass of the boxes should be the same.
