What two measurements are needed to calculate the density of a solid object?

• Mass and temperature

• Volume and color

• Mass and volume

• Height and width

How do you calculate the volume of a regularly shaped object?

• By multiplying its length, width, and height

• By using a thermometer

• By submerging it in water

• By measuring its mass

What was the mass of the stone in the first example?

• 1353g

• 1230g

• 1500g

• 1280g

What method is used to find the volume of an irregularly shaped object?

• Water displacement method

• Measuring its height and width

• Using a scale

• Using calipers

What was the volume of the irregularly shaped object in the second example?

• 300mL

• 175mL

• 38mL

• 50mL

What was the density of the irregularly shaped object?

• 5.5 g/cm3

• 7.9 g/mL

• 10.2 g/mL

• 2.77 g/cm3

What units are typically used to measure the volume of solid objects?

• Milliliters

• Liters

• Grams

• Cubic centimeters

What is the relationship between cubic centimeters and milliliters?

• 1 cubic centimeter is equal to 10 milliliters

• They are unrelated units

• They are equivalent units of volume

• 1 milliliter is equal to 10 cubic centimeters

What is the final step in calculating the density of a solid object?

• Measuring its temperature

• Finding its color

• Dividing its mass by its volume

• Calculating its height
