Numerical 1. Involving SF, BS & PLD Numerical 2.A Tween deck is 18 X 15 X 4 m and has a permissible load density of 5 t /m². Steel billets of SF 0.35 m³/t and general cargo of SF 4.0 m³/t are to be loaded therein to fill all the available space. Find the maximum quantity of steel billets that can be loaded and the quantity of over stowed general cargo so that load density is not exceeded
