# 002 Weight of snow ball

**Problem 002**

Find the weight of the snowball 1.2 m in diameter if the wet compact snow of which this ball is made weighs 480 kg/m^{3}

**Solution 002**

Radius of snowball

$r = \frac{1}{2}(1.2)$

$r = \frac{1}{2}(1.2)$

$r = 0.6 \, \text{ m}$

Volume of snowball

$V = \frac{4}{3}\pi r^3$

$V = \frac{4}{3}\pi (0.6^3)$

$V = 0.288\pi \, \text{ m^3}$

Weight of snowball

$W = \gamma V$

$W = 480(0.288\pi)$

$W = 434.3 \, \text{ kg}$
