// l = long
w = width
h = high
V = volume //
// unit conversion
1 liter = 1.000cm³
1 cm³ = 1 / 1.000liter //
l water = l tub - w concrete - w concrete
= 130cm - 5cm - 5cm
= 120cm
w water = w tub - w concrete - w concrete
= 90cm - 5cm - 5cm
= 80cm
h water = h bak - w concrete // only in less 1 times because the tub is generally not closed
= 70cm - 5cm
= 65cm
V water = l water × w water × t water
= 120cm × 80cm × 65cm
= 9.600cm² × 65cm
= 624.000cm³
= 624,000 (1 / 1,000liter)
= 624 liters
So the volume of water is 624 liters
