Question

A water tank in a form of a cuboid of height 22cm, length 7cm and width 5cm is filled with water. The water is then poured into a cylindrical container of diameter 14cm. Calculator the height of the water in the cylindrical container. [ Take π = 22/7]​

Answer 1

Answer: 5 cm

Explanation:

h = 22

l = 7

b = 5

volume of cuboid = lbh

= 22x7x5

=770 cm3

r = 7

770 = pi r^{2} h

770 = 22/7 x 49 x h

770 = 22 x 7 x h

110 = 22 x h

h = 5 cm
