A $25$ cm $25$ cm $1$ cm flat sheet weighing $1\mathrm{.}2$ kg initially was dried from both sides under constant drying rate conditions. It took $1500$ seconds for the weight of the sheet to reduce to $1\mathrm{.}05$ kg$.$ Another $1$m $1$m $1$cm flat sheet of the same material is to be dried from one side only. Under the same constant drying rate conditions, the time required for drying $($in seconds$)$ from its initial weight of $19\mathrm{.}2$ kg to $17\mathrm{.}6$ kg is
