amount of water poured in = 3(10) = 30 litres
= 30,000 cm^3
height of water without the stone --- h cm
h(40)(50) = 30000
h = 15 cm
when the stone is included, h = 18 cm
so the difference of 3 cm must have been caused by the stone
Volume for the extra 3 cm height
= 3(40)(50) = 6000 cm^3
volume of stone = 6000cm^3
= 30,000 cm^3
height of water without the stone --- h cm
h(40)(50) = 30000
h = 15 cm
