Lesson 18A Mass, Density, Volume

Front

What is the formula for calculating the volume of a cylinder?

Back

Volume = πr²h, where r is the radius and h is the height.

Front

What is the unit of measurement for mass?

Back

The unit of measurement for mass is grams (g).

Front

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

Back

Volume = Mass / Density.

Front

What is the density of an object?

Back

Density is the mass of an object divided by its volume, typically expressed in g/cm³.

Front

If a block of wood has a density of 0.6 g/cm³ and a mass of 120 g, what is its volume?

Back

200 cm³.

Front

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

Back

Density = Mass / Volume.

Front

How do you convert cm³ to ml?

Back

1 cm³ is equivalent to 1 ml.

Front

What is the formula for calculating the mass of an object given its volume and density?

Back

Mass = Density × Volume.

Front

If a gold brick measures 2 cm by 3 cm by 4 cm, what is its volume?

Back

Volume = Length × Width × Height = 2 cm × 3 cm × 4 cm = 24 cm³.

Front

What is the density of a substance with a mass of 48 g and a volume of 24 cm³?

Back

Density = Mass / Volume = 48 g / 24 cm³ = 2 g/cm³.
