the length,breadth and height of a cuboidal tank 150cm,120cm and 110cm.129600cm cube of water with hundred porus bricks each volume 2000cm .calculate rise in water level of the tank if each brick absorbs 1/10 of its volume.
volume absorbed of water absorbed is 129600-2000/10 = 129400 volume of tank is 150*120*110* = 1980000 volume of bricks is 2000 cm volume water is 129400+2000 = 131400 volume in rise is 131400-129600 = 1800 cm^3
length * breadth * rise is 1800 rise is 1800 / ( length * breadth ) =1800/18000 = 0.1 cm ANS : rise in level of water = 0.1 cm
