Density Word Problems and Practical

Front

What is density?

Back

Density is the mass of an object divided by its volume, typically expressed in grams per cubic centimeter (g/cm³) or grams per milliliter (g/mL).

Front

How do you calculate density?

Back

Density = Mass / Volume.

Front

What is the formula for finding the volume of a cube?

Back

Volume of a cube = side length × side length × side length (s³).

Front

If a cube has a mass of 3645 g and a height of 9 cm, what is its density?

Back

Density = 3645 g / (9 cm × 9 cm × 9 cm) = 5 g/cm³.

Front

What is the appropriate unit for measuring density?

Back

The appropriate unit for density is grams per cubic centimeter (g/cm³) or grams per milliliter (g/mL).

Front

What is the volume of a box measuring 20 cm x 8 cm x 14 cm?

Back

Volume = length × width × height = 20 cm × 8 cm × 14 cm = 2240 cm³.

Front

A rock has a mass of 54 g and occupies a volume of 20 cm³. What is its density?

Back

Density = 54 g / 20 cm³ = 2.7 g/cm³.

Front

What is the volume of a 500 g piece of metal with a density of 181.8 g/cm³?

Back

Volume = Mass / Density = 500 g / 181.8 g/cm³ = 2.75 cm³.

Front

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

Back

Mass is directly proportional to density and volume; as mass increases, density increases if volume remains constant.

Front

What is the unit for measuring volume?

Back

The unit for measuring volume is milliliters (mL) or cubic centimeters (cm³).
