Density and Volume Concepts

What is the relationship between mass and volume called?

• Weight

• Density

• Volume

• Mass

If two objects have the same volume, which one will have a higher mass?

• The one with larger size

• The one with higher density

• The one with lower density

• The one with smaller size

How is density calculated?

• Volume divided by mass

• Mass divided by volume

• Mass times volume

• Volume times density

What is the formula to find mass if density and volume are known?

• Density times volume

• Density divided by volume

• Mass divided by density

• Volume divided by density

In the first example, what is the density of the metal piece?

• 7.8 grams per cm³

• 0.85 grams per cm³

• 16 grams per cm³

• 8 grams per cm³

What is the volume of the iron statue in the second example?

• 897 cm³

• 50 cm³

• 115 cm³

• 7.8 cm³

Why is it important to ensure mass is in grams when using density in grams per cm³?

• To match the units of density

• To make calculations easier

• To simplify the formula

• To avoid using kilograms

What is the formula for the volume of a cylinder?

• 2πrh

• πr²h

• πr²

• 2πr²h

In the third example, what is the mass of the glass cylinder?

• 980 grams

• 2450 grams

• 7696 grams

• 3078 grams

How should the mass of the glass cylinder be ideally expressed?

• In pounds

• In grams

• In kilograms

• In milligrams
