A slab of a thermal insulator with a cross-sectional area of 115 cm2 is 4.00 cm thick. It is made out of red brick with thermal conductivity 0.600 J/s∙m•C°. The temperature difference between opposite faces is 95.0 C°. Calculate the following:

(a) The heat current through the slab

(b) The amount of heat flowing through the slab in two days

(c) The temperature gradient through the slab (unit: C°/cm)
