Question

A cylindrical container with a diameter of base 56cm contains sufficient water to submerge a rectangular solid of iron with dimensions 32cm 22cm 14cm Find a rise in the level of water when the solid is completely submerged

Accepted Answer

ANSWER Consider h cm as the rise in the level of water We know that Volume of a cylinder of height h and base radius 28cm volume of rectangular iron solid By substituting the values 227 282 h 32 22 14 On further calculation 22 28 4 h 32 22 14 So we get h 32 22 14 22 28 4 By division h 4cm Therefore the rise in the level of water when the solid is completely submerged is 4cm
