223.25

Explanation:

The thermal conductivity of an object is defined as the measure or the ability of the object to transfer heat or conduct heat through its body.

In the context, the thermal conductivity of the material is given as

And it is given that :

1 Btu = 1055 J

1 ft = 0.3048 m

We know that 1 h = 3600 s

So the thermal conductivity of the material in is  :

Thermal conductivity :

=  223.25
