Classwork 4/22 Volume or Surface Area

Front

What is Volume?

Back

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

Front

What is Surface Area?

Back

Surface Area is the total area that the surface of a three-dimensional object occupies, 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

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

Back

Volume = π × (2 cm)² × 5 cm ≈ 62.83 cm³.

Front

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

Back

Surface Area = 2πr(h + r) = 2π(2 cm)(5 cm + 2 cm) ≈ 87.96 cm².

What is the volume of a sphere with radius 3 cm?

Back

Volume = (4/3)π(3 cm)³ ≈ 113.1 cm³.

Front

What is the surface area of a sphere with radius 3 cm?

Back

Surface Area = 4π(3 cm)² ≈ 113.1 cm².
