Penjelasan dengan langkah-langkah:
Untuk memudahkan konversi, rubah semua satuan ke dm.
Ini karena [tex]\boxed {\sf \bf 1 \ dm^3 = 1 \ liter }[/tex].
[tex]\boxed {\sf NOMOR \ 1 }[/tex]
Kedalaman / rusuk = s = 1 m [tex]\iff[/tex] 10 dm
Volume = [tex]\sf s \times s = 10 \times 10 = 100 \ dm^3 \iff \underline {\boxed {\blue {\sf \bf 100 \ liter }}}[/tex]

Lebar (l) = 150 cm [tex]\iff[/tex] 15 dm
Kedalaman = tinggi (t) = 80 cm [tex]\iff[/tex] 8 dm
Daya tampung kolam = Volume= [tex]\sf p \times l \times t = 30 \times 15 \times 8 = 3.600 \ dm^3 \iff \underline {\boxed {\blue {\sf \bf 3.600 \ liter}}}[/tex]
