The answer to this problem is a$.$ Solve the surface temperature at that time. Do not need to show got they got to a$.$ I am asking for the surface temperature steps and calculations only please. Thx$.$

A block of cheddar cheese that is $16\mathrm{.}5-cm$ thick

$m$ with properties $k=0\mathrm{.}35\frac{W}{m}*K$ and $=0\mathrm{.}12{10}^{-6}\frac{m^2}{s}$

is initially at an even temperature of
