Use density = mass ÷ volume to find density, mass or volume, and decide whether objects sink or float in water. There are 2 sheets here: density problems and more density problems. Pick one from the tray, print it, and add its answer key as a second page if you want one.

Density problems
Density = mass ÷ volume. Show the formula, the numbers and the units.
A liquid has a density of 1.5 g/mL. What is the mass of 20 mL?
A metal has a density of 11.3 g/cm³ and a mass of 192.1 g. What is its volume?
A metal has a density of 0.8 g/cm³ and a mass of 2.4 g. What is its volume?
A liquid has a density of 8.9 g/mL. What is the mass of 34 mL?
A metal has a density of 8.9 g/cm³ and a mass of 382.7 g. What is its volume?
A liquid has a density of 2.5 g/mL. What is the mass of 2 mL?
A metal has a density of 7.9 g/cm³ and a mass of 268.6 g. What is its volume?
Water has a density of 1.0 g/mL. Will an object with a density of 0.8 g/cm³ sink or float in water?
Using these sheets
New problems gives the same kind of sheet with different numbers, so you can print one for class and another for homework.
The answer key matches the sheet on screen, including after you make new problems.
Sheets print on US Letter paper. On A4, choose “Fit to printable area” in the print dialog.
Questions
What grade are these density worksheets for?
They suit grades 6 to 10. Each sheet in the tray practices it a different way, so you can pick the one that fits.
Is there an answer key?
Yes. Tick “add the answer key as page 2” before printing, or turn on Answer key to check work on screen.
Can I print more than one version?
Yes. Press New problems for a fresh set of the same kind, then print again. The answer key changes with it.
Do I need an account to print?
No. The sheets print straight from this page, free, with no sign-up.
