More information is required to answer this question. A litre is a volume measure (3 dimensions) but information for the pond is given for only two dimensions.
We have no way of knowing how much water is in any particular volume of space.But 2.1 cubic meters = 2,100 liters .
65 as a cubic metre is 1000 litres
1 cu m = 1000 liters → volume = 2 m x 3 m x 1 m = 6 cu m = 6 x 1000 liters = 6,000 liters.
9 Acres = 36,421.7 square meters. 4 feet = 1.2 meters. Area x length = volume; 36,421.7 x 1.2 = 43,706 cubic meters. Cubic meters is a volume, which can be converted to liters, 1 cubic meter is 1000 liters. So your pond has 43,706,000 Liters. 1 gallon is 3.78 liters, so divide by 3.78 and your pond has 11,545,903.7 Gallons.
liters
Liters. Or MegaLiters (x1 000 liters)
1359.2 litres, approx.
The volume is 13592 litres, approx.
You don't really need to measure the water in a birdbath, just put some in a couple inches deep.
lenght times width times height = volume so whats 2 times 1 times 500?
509.7 litres
A 'pond' is a body of water.
