Which observation allows you to tell that two cubes are made of different metals? select the two correct answers.
a. their volumes are the same, and their masses are the same.
b. their volumes are the same, and their masses are different.
c. their volumes are different, and their masses are the same.
d. their volumes are unknown, and their masses are the same.
e. their volumes are the same, and their masses are unknown

Option B,  Their volumes are the same, and their masses are different.

Explanation:

Two metallic cubes made of different metal types can have same volume and shape and size but their weight will always be different due to difference in physical properties such as density.

For example two cubes of volume 10 cubic meter each have same volume but since one cube is made up of aluminium and the other cube is made up of iron, both the two cubes with similar shape, size and volume will have different mass

Hence, option B is correct.
