Question

On your lab bench, you have 2 mystery metal cubes. each cube has a mass of 10.0 grams. cube a has a density of 10 g/cm3. cube b has a density of 0.37 cm3. what conclusion can be made about the sizes of the two cubes?

a. cube b has atoms that are more closely packed in its volume than cube
a.
b. cube b has a volume that is one-third of the volume of cube
a.
c. each edge of cube b is two times larger than cube
a.
d. each edge of cube b is three times larger than cube

Answer 1

To compare both, we find the volume of both cubes as follows:

V of cube A = 10 g / 10 g/cm^3 = 1 cm^3

V of cube B = 10 g / 0.37 g/cm^3 = 27 cm^3

I think the correct answer from the choices listed above is option D. Each edge of cube b is three times larger than cube. Hope this helps. Have a nice day.
