A teacher gives her students a small aluminum cube. She shows them a table that has a list of properties of the cube. The table is shown below.
Properties of Aluminum Cube Value
length of each side
1.0 cm
volume
1.0 cm3
660°C

mass
2.7 g
The students are then asked to test to see if a different metal cube is made of aluminum. Which single property listed on the table
would best help the students determine this?
OA. length of each side
ОВ.
mass
C.
volume
D.
melting point
