Question

a measuring cylinder contains water to a level of 40 ml the water level Rises to 48 ml when a piece of brass is completely immersed in it find the volume of brass in a-centimetre cube b- metre cube​

Answer 1

Answer:

The volume of the brass will be equal to the rise in the volume of water.

So volume of brass =

$48 - 40 \: ml \\ 8 \: ml$

Since 1

$1 {m}^{3} = 1000 \: litre \\ and \: 1litre = 1000 \: ml \\ so \\ 1ml = {10}^{ - 6} {m}^{3} = {10}^{ - 12} {cm}^{3 } \\ 8ml = 8 \times {10}^{ - 12} \: {cm}^{3 }$

And volume of brass in meter qube

$= 8 \times {10}^{ - 6} \: {m}^{3}$
