Question

A cylindrical container with diameter of base 48 cm contains sufficient water to submerge a rectangular solid of iron with dimensions 33 cm x 18 cm x 12 cm. Find the rise in the level of water when the solid is completely submerged.

Answer 1

the rise in level of water means increase in h
volume of the solid cuboid is equal to volume of water increased

33*18*12=π(24^2) *h
33*18*12=π*24*24*h
$\\ (33 \times 18 \times 12 \times 7) \div (22 \times 24 \times 24)$
