A) 9 g/cm3 B) 70 g/cm3 C) 441 g/cm3 D) 56 g/cm3

2. An object has a mass of 10 g and volume of 2 cm3. What is its density?

A) 12 g/cm3 B) 8 g/cm3 C) 5 g/ cm3 D) 20 g/cm3

3. What is the volume of a box 5 cm long, 4 cm wide and 6 cm high?120 cm3

4. A cube has a width of 2 cm. What is the cube’s volume?8 cm3

5. A student was testing 4 substances during an experiment and recorded the data in the table below.

Substances / Mass (g) / Volume (mL)
A / 10 g / 2 mL
B / 12 g / 6 mL
C / 16 g / 4 mL
D / 75 g / 5 mL
