	$w o o d a l o n e i n l i q u i d :$ $ρ_{W} V_{W} = ρ_{L} V_{L}$ $ρ_{W} = \frac{V_{L}}{V_{W}} ρ_{L} = \frac{75}{100} \times 1.2 = 0.9$ $w o o d w i t h g l a s i n l i q u i d :$ $ρ_{G} V_{G} + ρ_{W} V_{W} = ρ_{L} (V_{G} + V_{W})$ $(ρ_{G} - ρ_{L}) V_{G} = (ρ_{L} - ρ_{W}) V_{W}$ $V_{G} = \frac{(ρ_{L} - ρ_{W}) V_{W}}{ρ_{G} - ρ_{L}} = \frac{1.2 - 0.9}{2.4 - 1.2} \times 100 = 25 {c m}^{3}$ $m_{G} = 1 \times ρ_{G} V_{G} = 1 \times 2.4 \times 25 = 60 g$
