Density Quiz

What is the formula to calculate density?

• Density = Mass * Volume

• Density = Volume / Mass

• Density = Weight / Volume

• Density = Mass / Volume

Aarav found a small object in his science lab which has a mass of 50g. Anaya measured its volume and found it to be 10cm³. Chloe is curious to know, what is the density of the object?

• 15 g/cm³

• 5 g/cm³

• 2 g/cm³

• 10 g/cm³

A block of wood has a volume of 100cm³ and a density of 0.5g/cm³. What is its mass?

• The mass of the block of wood is 25g

• The mass of the block of wood is 50g

• The mass of the block of wood is 100g

• The mass of the block of wood is 75g

Daniel has a block of metal that has a mass of 200g. Arjun measures the volume of the block and finds it to be 50cm³. What is the density of the metal block?

• 4 g/cm³

• 2 g/cm³

• 10 g/cm³

Aiden has a toy block with a density of 2g/cm³ and a volume of 20cm³. If he puts it in his water tub, will it float or sink?

• The toy block will evaporate in water.

• The toy block will stay suspended in water.

• The toy block will float in water.

• The toy block will sink in water.

A metal ball has a mass of 100g and a volume of 40cm³. Will it float or sink in water?

• The metal ball will stay suspended in water because its density is equal to the density of water.

• The metal ball will float in water because its density is less than the density of water.

• The metal ball will dissolve in water because its density is too high.

• The metal ball will sink in water because its density (2.5 g/cm³) is greater than the density of water (1 g/cm³).

Oliver found a rock weighing 300g. If the density of the rock is 3g/cm³, what is the volume of the rock?

• The mass of the object is 100g

• The mass of the object is 50g

• The mass of the object is 25g

Benjamin found an irregular shaped rock while hiking. He measured its mass and found it to be 150g. When he submerged it in water, he noticed that the water level rose by 75cm³. What is the density of the rock that Benjamin found?

• 2 g/cm³

• 150 g/cm³

• 0.5 g/cm³
