Use a calculator to determine the density. 16. What is the density of the cube if the mass is 24g?

15. Use a calculator to determine the density.
16. What is the density of the cube if the mass is 24g?
17. Use the image below to find the density of a ring that has a mass of 32g.
18. A metal ruler has a mass of 42g and a volume of 10cm³. What is the density?
19. What is the density of the rectangular prism if the mass is 90g?
20. Use the image below to find the density of a rock that has a mass of 60g.

Answer

  1. 15. The density is 19.3 g/cm³.

  2. 16. Density = Mass / Volume = 24g / (2cm * 2cm * 2cm) = 24g / 8cm³ = 3 g/cm³.

  3. 17. Use the image to find the volume displaced by the ring, then calculate density = Mass / Volume.

  4. 18. Density = Mass / Volume = 42g / 10cm³ = 4.2 g/cm³.

  5. 19. Density = Mass / Volume = 90g / (5cm * 2cm * 1cm) = 90g / 10cm³ = 9 g/cm³.

  6. 20. Use the image to find the volume displaced by the rock, then calculate density = Mass / Volume.
