    P = 9.93 \left( \sqrt{fc} \right) \left( te^2 \right) \left( \left( \frac{k}{{19000 \left( \sqrt{fc} \right) \left( te^3 \right)}} \right) ^{0.25} \right)

    The variables used in the formula are:

    fc = Concrete compressive strength,

    k = Modulus of subgrade reaction,

    te = Slab thickness.
