16. A cylindrical can of internal radius 20 cm stands upright on a flat surface. It contains water to a depth of 20 cm . Calculate the rise in the level of the water when a brick of volume \( 1500 \mathrm{~cm}^{3} \) is immersed in the water. 17. A cylindrical tin of height 15 cm and radius 4 cm is filled with sand from a rectangular box. How many times can the tin be filled if the dimensions of the box are 50 cm by 40 cm by 20 cm ? 18. Rain which falls onto a flat rectangular surface of length 6 m and width 4 m is collected in a cylinder of internal radius 20 cm . What is the depth of water in the cylinder after a storm in which 1 cm of rain fell?
