What is the formula for the volume of a sphere?

Back

V = (4/3)πr³, where r is the radius.

Front

How do you calculate the volume of a cone?

Back

V = (1/3)πr²h, where r is the radius and h is the height.

Front

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

Back

V = l × w × h, where l is the length, w is the width, and h is the height.

Front

What does the 'B' represent in the volume formula V = Bh for a cylinder?

Back

B represents the area of the base of the cylinder.
