Question

a cylindrical tank of radius 7m has a water to some level if 110 cubes of sides is 7m are completely immersed in it ,then find the rise in water level​

Answer 1

cylinder

radius = 7 m

cube

side = 7m

total no of cube = 110

1)

volume of cylinder = πr^2 h

= 22/7×7×7×h

= 154h

2)

volume of the cube = l^3

= 7^3

= 343

no of cubes = volume of the cylinder/ volume of the cube

110 = 154h / 343

110×343/154 = h

37730/343 = h

h. = 245 m

Answer 2

Answer:

rise in water level h1=245m
