Question

If a person has a large piece of aluminum the size of a table, and a small piece of aluminum

the size of a pencil, which one will have a greater density?

Page 51: 200 300 400 Final 100 200 300 400 500 100 200 300 400 500 100 200 300 400 500 100 200 300 400 500 100 Vocab Measuring Tools Volume & Density Safety Precautions.

AnswerThey will have the same density because

density measures the grams per cubic centimeter. Since both of the pieces are

made out of aluminum, the densities are going to be the exact same.
