lenght times width times height = volume so whats 2 times 1 times 500?
1359.2 litres, approx.
It's unlikely that your pond has vertical sides and is 3' deep everywhere, but if it were, it would hold 18 * 7 * 3 = 378 cu. ft. of water. Converting the dimensions to metric at the start makes everything easier. 378 * (12^3) * (2.54^3) give you the number of cc's, dividing that by 1000 gives you the number of liters (10703). Dividing THAT by 3.7854 (liters/gallon) gives you about 2828 gallons. A typical pond, however, probably slopes from very shallow at the periphery to maximum depth near the center. This means it likely holds 30 - 40% less than if it had steep vertical sides and a consistent depth (like a typical above-ground pool). Your pond is probably on the order of 1500 - 1900 gallons.
Litres.
29 days... with exponential growth and reaching 100% of pond coverage in 30 days, it will be 50% (or 1/2) of its size on the 29th day...and one day later - double in size to reach full pond cover. BF Trinidad
i need help
We have no way of knowing how much water is in any particular volume of space.But 2.1 cubic meters = 2,100 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.
You don't really need to measure the water in a birdbath, just put some in a couple inches deep.
65 as a cubic metre is 1000 litres
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.
1 cu m = 1000 liters → volume = 2 m x 3 m x 1 m = 6 cu m = 6 x 1000 liters = 6,000 liters.
liters
Liters. Or MegaLiters (x1 000 liters)
9,510.19 Gallons
It would be 0.3 metres.
A pond pump helps circulate the water properly. If it is not used, the water would sit still and get slimy. If there are fish in the pond it would help keep the water clean.
