Question

A cylindrical jar whose radius as 42cm
is paretly filled with water. If a
rectangular block of dimension 24cm x 21 cm x 11cm is wholely immersed in
water of the jar by how much will
the level of water rise.​

Answer 1

Answer:

so now...

volume of a cuboid = l*b*h

=24*21*11cm3

keep tis as it is...

volume of cylinder=

$\pi \: r {}^{2} h$

substitute tis

22 /7*42*42*h

22*6*42*hcm3

keep it as it is

now..

volume of cylinder=volume of a cuboid

24*21*11=22*6*42*h

h=24*21*11/22*6*42=

h=1cm
