A) l=70; b= 44m and h= 10 cm = 0.1 m

So, volume of water on roof = lbh =

70×44×0.1=308m3 (As, the rainwater will form

a cuboidal shaped solid on the roof)

(b) Let h be the height of the water in the tank.

Volume of the water in

tank=πr2h=227×142h=616h

As, the water is falling to the tank from the roof,

So 308= 616h

h= 308/616=0.5 m

Answer 2

A) l=70; b= 44m and h= 10 cm = 0.1 mSo, volume of water on roof = lbh =70×44×0.1=308m3  (As, the rainwater will forma cuboidal shaped solid on the roof)

(b) Let h be the height of the water in the tank.Volume of the water intank=πr2h=227×142h=616hAs, the water is falling to the tank from the roof,

So 308= 616h

h= 308/616=0.5 m
