Volume of a bucket 84 cm high, diameter of top as 40 cm and radius of bottom as 10 cm is

The bucket forms a frustum of a cone with height h = 84 cm, lower radius r = 10 cm, and upper radius R = 20 cm. Using the frustum volume formula V = (1/3) * pi * h * (R^2 + r^2 + R * r), we get V = (1/3) * pi * 84 * (20^2 + 10^2 + 20 * 10). Simplifying this yields 28 * pi * 700, which equals 19600 * pi, resulting in approximately 61.6 liters.
