Calculating Density

Front

What is the formula to calculate volume of a rectangular prism?

Back

Volume = Length x Width x Height (L x W x H)

Front

What is density?

Back

Density is a measure of how much mass is contained in a given volume. It is calculated using the formula Density = Mass/Volume.

Front

How do you find the volume of an object submerged in water?

Back

The volume of the object can be found by measuring the change in water level in a graduated cylinder or beaker after the object is submerged.

Front

What is the unit of measurement for density?

Back

Common units for density include grams per cubic centimeter (g/cm³) or kilograms per cubic meter (kg/m³).

Front

If an object has a mass of 30 grams and a volume of 10 cm³, what is its density?

Back

Density = Mass/Volume = 30g/10cm³ = 3g/cm³.

Front

What happens to the water level when an object is placed in a beaker?

Back

The water level rises by an amount equal to the volume of the object placed in the beaker.

Front

What is the volume of a cube with a side length of 4 cm?

Back

Volume = Side x Side x Side = 4cm x 4cm x 4cm = 64 cm³.

Front

How do you calculate the mass of an object if you know its density and volume?

Back

Mass = Density x Volume.

Front

What is the relationship between mass, volume, and density?

Back

Density is the ratio of mass to volume; as mass increases with constant volume, density increases, and vice versa.

Front

If a ring displaces 2 cm³ of water when submerged, what is the volume of the ring?

Back

The volume of the ring is 2 cm³.
