Part $($a$)$

What is the mass of this iceberg, in kilograms, given that the density of ice is $917k\frac{g}{m^3}?$

Part $($b$)$

How much heat, in joules, must be transferred to the iceberg to melt it$?$ Assume the ice is at $0C,$ and the latent heat of fusion for water is $L_f=79\mathrm{.}8$kca$\frac{l}{k}g.$

Part $($c$)$

How long, in years, would it take sunlight alone to melt ice this thick, if the ice absorbs an average of $100\frac{W}{m^2},12\mathrm{.}00$ hours per day?
