At `20^(@)C` a liquid is filled upto `10` cm height in a container of glass of length `20` cm and cross-sectional area `100 cm^(2)` . Scale is marked on the surface of container. This scale gives correct reading at `20^(@)C` . Given `gamma_(L) = 5 xx 10 ^(-5) k^(-1) , alpha^(g) = 1 xx 10^(-5) "^(@)C^(-1)`

The actual height of liquid at `40^(@)C` is -
