Problem $1-10$ pts

Sokka is making a new sword and needs to quench it$.$ The sword blade has a surface area of $35i{n}^2$

and volume of $2\mathrm{.}5i{n}^3.$ It is made out of a material with a thermal conductivity of $40BT\frac{U}{h}r-ft-F,$

density of $490l\frac{b}{f}{t}^3,$ and specific heat of $0\mathrm{.}104BT\frac{U}{l}b-F.$ Before quenching, Sokka heats the

sword blade to $2000F$ and then submerges it in oil at
