Q$3(10$ m$)$:

It takes some time for Heat to transfer from one side of a wall to the other side.

The formula $t=\frac{L^2}{16}$ is used to calculate the time. Where,

T is the time in seconds for back of the wall to feel heat

$L$ is the wall thickness in meters and

$$ is a constant: $1\mathrm{.}2{10}^{-6}\frac{m^2}{s}$

Calculate the time it would take the heat to transfer through a $6$ inch block wall.
