A steel tape `1 m` long is correctly calibrated for a temperature of `27.0^(@)C`. The length of a steel rod measured by this tape is found to be `63.0 cm` on a hot day when the temperature is `45^(@)C`. Coefficient of linear expansion of steel `= 1.20 xx 10^(-5) //K`. what is the actual length of the steel rod on that day?
