A rectangular container is 20 cm long, 11 cm wide and 15 cm high. The container is filled with water to a depth of 10 cm.
A metal sphere of radius 3.9 cm is placed in the water. It sinks to the bottom.
Volume of sphere=43πr3 \text{Volume of sphere} = \frac{4}{3}\pi r^3 Volume of sphere=34πr3 Surface area of sphere=4πr2 \text{Surface area of sphere} = 4\pi r^2 Surface area of sphere=4πr2
Calculate the rise in the water level. Give your answer correct to 3 significant figures.
