Question

Zoe is shown two mystery boxes that are both 8,000cm3. Her teacher tells her that one mystery box is filled with rocks and the other is filled with napkins. Without touching the boxes, Zoe is asked to determine which box has the napkins.

Answer 1

The box of rocks will have depression which can be seen without touching the box.

Step-by-step explanation:

The density of rocks is very large as compared with napkins. So, the weight of the rocks will be much more greater than that of napkins.

As both boxes have same volume the heavier box will show depression on the lower surface as compared to the lighter box. So, the box of rocks will have depression which can be seen without touching the box.
