A square footing of $4 m$ side is placed at $1 m$ depth in a sand deposit. The dry unit weight $(\gamma)$ of sand is $15 \mathrm{kN} / \mathrm{m}^{3}$. This footing has an ultimate bearing capacity of $600 \mathrm{kPa}$. Consider the depth factors: $d_{q}=d_{\gamma}=1.0$ and the bearing capacity factor: $N_{\gamma}=18.75 .$ This footing is placed at a depth of $2 \mathrm{~m}$ in the same soil deposit. For a factor of safety of 3.0 as per Terzaghi's heory, the safe bearing capacity (in $k P a$ ) of this footing would be
