Question

A cylindrical jar is 20 cm high with internal diameter 7 cm an iron cube of edge 5 cm is immersed in the jar completely in the water which was originally 12 cm high find the rise in the level of water

Answer 1

Answer:

the water will rise by 3.247 CM

Step-by-step explanation:

the internal radius of a cylinder = 7/2. = 3.5 cm

the volume of cube = 5×5×5

= 125 cm cube

the volume of water displaced = volume of the cube

if the rise in height = h

volume of water displaced = 22/7 × 3.5^2 × h = 125

h = 125 × 7/22/3.5^2

= 3.247 cm

I hope this will help you
