A rectangular container is 5 cm. wide and 12 cm. long and contains water to a depth of 7 cm. A stone is placed in the water and the water rises 1.7 cm. Find the volume of the stone.

volume without the stone = 5x12x7 = 420
volume with the stone = 5x12x8.7 = 522
for an increase of 102 cm^3 , so according to Archimedes that increase would have been caused by the volume of the stone.
