Question

from a cubical tank of side 12cm, which is full of water ,the content is poured into a cylindrical vessel of radius 3.5cm .what will be the height of the water level in the vessel?

Answer 1

volume of cube =volume of water =(side)^3
(12)^3= 1728cm^3

as same amt of water is poured in cylinder of dia. 7cm

volume of cyl=volume of cube

$\pi \div 4 \times 7 ^{2} \times l = 1728$
L= 44.90 cm
