Question

a rectangular has base dimensions of 2.5 by 1.5 m and a height of 1.2 m is 80% filled with water. If the water is transfered into a cylindrical tank with a diameter of 80 cm, how high will the water level rises

Answer 1

volume of cuboid = 2.5*1.5*1.2

=4.5 cubic metre

volume of water filled = 80/100*4.5

=3.6 cubic metre

if d=80 cm then r=0.4 m

Let's assume cylinder volume to be volume of water

Hence, 3.6=22/7*0.4*0.4*h

3.6=0.502h(approx.)

36/10*1000/502=h

7.171 m=height of water
