sebuah kamar mandi berukuran 1 1/2 m × 4/5 × 3/5m. jika bak tersebut terisi 2/3 bagian,berapa liter volume air dalam bak tersebut

1 liter = 1 dm3
Volume air =
[tex] \frac{2}{3} \times (1 \frac{1}{2} \times \frac{4}{5} \times \frac{3}{5} ) \\ = \frac{2}{3} \times ( \frac{3}{2} \times \frac{4}{5} \times \frac{3}{5} ) \\ = \frac{2}{3} \times ( \frac{15}{10} \times \frac{8}{10} \times \frac{6}{10} ) \\ = \frac{2}{3} \times (1.5 \: m \times 0.8 \: m \times 0.6 \: m) \\ = \frac{2}{3} \times (15 \: dm \times 8 \: dm \times 6 \: dm) \\ = \frac{2}{3} \times 720 \\ = 2 \times 240 \\ = 480 \: {dm}^{3} = 480 \: liter[/tex]
Semoga membantu :-)
