8a) Density, volume, mass of objects

What is density?

• The amount of mass an object has.

• The amount of space an object occupies.

• The amount of substance in a measured 3D space.

• The weight of an object in a given area.

Which of the following are common units for measuring volume?

• Grams (g) or Kilograms (kg)

• Centimeters (cm) or Meters (m)

• Cubic centimeters (cm³) or Milliliters (mL)

• Pounds (lb) or Ounces (oz)

• Yes

• No

How is density calculated?

• Mass multiplied by Volume

• Volume divided by Mass

• Mass divided by Volume

• Weight divided by Area
