Sebuah aquarium berbentuk balok dengan ukuran p = 50 cm, l = 30 cm dan t = 25 cm, tiga buah batu dimasukkan kedalam aquarium sedemikian hingga airnya tumpah sebanyak 0,6 liter, Jika ketinggian air mula-mula 20 cm, maka rata-rata volume batu adalah...

P = 5 dm, l = 3 dm, t = 2.5 dm Volume total = p*l*t = 5 dm * 3 dm * 2.5 dm = 37.5 dm^3 = 37.5 liter Volume awal dg t = 20 cm = 2 dm Volume awal = p*l*t = 5 dm * 3 dm * 2 dm =30 dm^3 = 30 liter saat 3 batu dimasukkan tumpah 0.6 liter, maka volume 3 batu tsb = (37.5 liter - 30 liter ) + 0.6 liter = 7.5 + 0.6 = 8.1 liter rata" volume batu = 8.1 liter / 3 = 2.7 liter
Volume total = p*l*t = 5 dm * 3 dm * 2.5 dm = 37.5 dm^3 = 37.5 liter
Volume awal dg t = 20 cm = 2 dm
Volume awal = p*l*t = 5 dm * 3 dm * 2 dm =30 dm^3 = 30 liter
saat 3 batu dimasukkan tumpah 0.6 liter, maka volume 3 batu tsb = (37.5 liter - 30 liter ) + 0.6 liter = 7.5 + 0.6 = 8.1 liter
rata" volume batu = 8.1 liter / 3 = 2.7 liter
