What is the formula for calculating density?

• Density = Mass × Volume

• Density = Mass ÷ Volume

• Density = Volume ÷ Mass

• Density = Mass + Volume

If a rock has a mass of 200 grams and a volume of 50 cubic centimeters, what is its density?

• 2 grams per cubic centimeter

• 4 grams per cubic centimeter

• 6 grams per cubic centimeter

• 8 grams per cubic centimeter

What does density measure?

• The weight of an object

• How tightly matter is packed together

• The color of an object

• The temperature of an object

Why is understanding density important?

• It helps us determine the color of materials

• It helps us compare different materials and predict whether objects will float or sink

• It helps us measure the temperature of objects

• It helps us calculate the speed of objects

What is the density of an object with a mass of 100 grams and a volume of 25 cubic centimeters?

• 2 grams per cubic centimeter

• 3 grams per cubic centimeter

• 4 grams per cubic centimeter

• 5 grams per cubic centimeter
