Practice questions on Physics Numericals - Density — with answers

Try each question first, then open the answer. Explanations are included.

1. An object has a mass of 620 g and a volume of 10 cm^3. What is its density?

A86.80 g/cm^3
B62.50 g/cm^3
C62 g/cm^3
D61.50 g/cm^3

Show answer

Answer: C

Density = Mass / Volume = 620 / 10 = 62 g/cm^3.

2. An object has a mass of 740 g and a volume of 87 cm^3. What is its density?

A11.91 g/cm^3
B8.51 g/cm^3
C9.01 g/cm^3
D8.01 g/cm^3

Show answer

Answer: B

Density = Mass / Volume = 740 / 87 = 8.51 g/cm^3.

3. An object has a mass of 810 g and a volume of 23 cm^3. What is its density?

A35.72 g/cm^3
B49.30 g/cm^3
C35.22 g/cm^3
D34.72 g/cm^3

Show answer

Answer: C

Density = Mass / Volume = 810 / 23 = 35.22 g/cm^3.

A8.13 g/cm^3
B10.68 g/cm^3
C7.63 g/cm^3
D7.13 g/cm^3

Show answer

Answer: C

Density = Mass / Volume = 595 / 78 = 7.63 g/cm^3.

5. An object has a mass of 675 g and a volume of 91 cm^3. What is its density?

A7.92 g/cm^3
B7.42 g/cm^3
C10.38 g/cm^3
D6.92 g/cm^3

Show answer

Answer: B

Density = Mass / Volume = 675 / 91 = 7.42 g/cm^3.
