Mastering Density Calculations with the DMV Triangle

The video tutorial explains how to calculate density, mass, and volume using a triangle method. It provides examples for each calculation: finding density from mass and volume, finding mass from density and volume, and finding volume from mass and density. The tutorial emphasizes the use of a mnemonic 'DMV' to remember the relationships between these quantities.

What is the formula for density using the DMV triangle?

• Density = Mass x Volume

• Density = Mass / Volume

• Density = Volume / Mass

• Density = Volume x Mass

If a cake has a mass of 500 grams and a volume of 2500 cm3, what is its density?

• 5 grams/cm3

• 0.5 grams/cm3

• 0.2 grams/cm3

• 2 grams/cm3

What is the density of a block of wood with a mass of 6 grams and a volume of 12 cm3?

• 2 grams/cm3

• 0.5 grams/cm3

• 0.6 grams/cm3

• 1 grams/cm3

How do you calculate mass using the DMV triangle?

• Mass = Volume x Density

• Mass = Density x Volume

• Mass = Volume / Density

• Mass = Density / Volume

A substance has a density of 8 grams/cm3 and a volume of 25 cm3. What is its mass?

• 200 grams

• 100 grams

• 50 grams

• 400 grams

What is the formula for volume using the DMV triangle?

• Volume = Mass x Density

• Volume = Density / Mass

• Volume = Density x Mass

• Volume = Mass / Density

A weight has a mass of 820 grams and a density of 5 grams/cm3. What is its volume?

• 205 cm3

• 82 cm3

• 164 cm3

• 410 cm3

Which of the following is NOT a correct use of the DMV triangle?

• Mass = Density x Volume

• Volume = Density x Mass

• Density = Mass / Volume

• Volume = Mass / Density

If the density of a material is 5 grams/cm3 and its mass is 100 grams, what is its volume?

• 30 cm3

• 20 cm3

• 25 cm3

• 15 cm3

What happens to the units when calculating mass from density and volume?

• Units remain the same

• Units cancel out

• Units change to grams

• Units change to cm3
