Sean wants to know what kind of metal a model soldier is made of. He decides to calculate its density. In order to calculate the density of the model soldier, Sean needs to find out its mass and volume.

Sean measures its mass to be 173.5 grams using a triple beam balance. Next, he fills a graduated cylinder with 50 mL of water. He drops the model soldier into the water. With the soldier in it, the graduated cylinder reads 65.3 mL.

What is the volume of the model soldier?
A.174 cm3
B.2.7 cm3
C.65.3 cm3
D,15.3 cm3

D) 15.3 To find the volume of something, you measure the amount of water it displaced. In this case, mL is used for the measurement. Since the graduated cylinder reads 65.3 mL, you know they're talking about liquid measurement, therefore, it must be water. 65.3 - 50 is 15.3. Therefore, the mass of the toy soldier is 15.3.
