Penyelesaian :

Volume keseluruhan akuarium =

\begin{gathered}p \times l \times t \\ \\ 60 \times 30 \times 35 \\ \\ 1.800 \times 35 \\ \\ 63.000 \: cm {}^{3} \end{gathered}

p×l×t

60×30×35

1.800×35

63.000cm

3

Yang terisi 3/4 bagian

\begin{gathered} \frac{3}{4} \times 63.000 \\ \\ \frac{189.000}{4} \\ \\ 47.250\end{gathered}

3

×63.000

4

189.000

47.250

Jadi, banyak air jika harus terisi penuh =

\begin{gathered}63.000 \: cm {}^{3} - 47.250 \: cm {}^{3} = \\ \\ 15.750 \: cm {}^{3} \end{gathered}

63.000cm

3

−47.250cm

3

=

15.750cm
