To calculate the volume of the punching bag, you can use the formula for the volume of a cylinder, which is V = πr^2h, where V is the volume, π is a constant (approximately 3.14), r is the radius, and h is the height. Since the punching bag is a cylinder, you can use the given dimensions to calculate the volume. First, you need to find the radius by dividing the width by 2 (r = 35cm / 2 = 17.5cm). Then, you can calculate the volume using the formula V = 3.14 * (17.5cm)^2 * 120cm. This will give you the amount of space inside the punching bag in cubic centimeters. **
