What is Volume?

Back

Volume is the amount of space an object occupies, measured in cubic units.

Front

What is Surface Area?

Back

Surface Area is the total area of the surface of a three-dimensional object, measured in square units.

Front

How do you calculate the Volume of a rectangular prism?

Back

Volume = length × width × height.

Front

How do you calculate the Surface Area of a rectangular prism?

Back

Surface Area = 2(length × width + length × height + width × height).

Front

What is the Volume of a cube with side length 3 cm?

Back

Volume = 3 cm × 3 cm × 3 cm = 27 cm³.

Front

What is the Surface Area of a cube with side length 4 cm?

Back

Surface Area = 6 × (4 cm × 4 cm) = 96 cm².

Front

When would you use Volume instead of Surface Area?

Back

Use Volume when measuring how much space an object can hold, like liquid in a bottle.

Front

When would you use Surface Area instead of Volume?

Back

Use Surface Area when measuring the amount of material needed to cover an object, like wrapping paper for a gift.

Front

What is the Volume of a cylinder with a radius of 2 cm and height of 5 cm?

Back

Volume = π × radius² × height = π × (2 cm)² × 5 cm ≈ 20π cm³.

Front

What is the Surface Area of a cylinder with a radius of 2 cm and height of 5 cm?

Back

Surface Area = 2πr(h + r) = 2π(2 cm)(5 cm + 2 cm) = 28π cm².
