What is the formula for the volume of a rectangular prism?

Back

Volume = length × width × height

Front

How do you calculate the volume of a cone?

Back

Volume = (1/3) × π × r² × h, where r is the radius and h is the height.

Front

What is the value of π (pi) used in volume calculations?

Back

π (pi) is approximately 3.14.

Front

What is the formula for the volume of a pyramid?

Back

Volume = (1/3) × base area × height.

Front

How do you round a number to the nearest whole number?

Back

Look at the digit after the decimal point: if it's 5 or more, round up; if it's less than 5, round down.

Front

What is the volume of a cylinder?

Back

Volume = π × r² × h, where r is the radius and h is the height.

Front

If a rectangular prism has dimensions 10 cm, 5 cm, and 3 cm, what is its volume?

Back

Volume = 10 cm × 5 cm × 3 cm = 150 cm³.

Front

What is the volume of a cone with a radius of 3 inches and a height of 5 inches?

Back

Volume = (1/3) × π × (3 in)² × (5 in) = 15.7 in³ (using π ≈ 3.14).

Front

How do you find the volume of a composite figure?

Back

Calculate the volume of each individual shape and then sum them up.

Front

What is the volume of a rectangular pyramid with a base area of 24 cm² and a height of 6 cm?

Back

Volume = (1/3) × 24 cm² × 6 cm = 48 cm³.
