Due to refraction. When light travels through a denser substance, it bends towards the normal, so things appear to be at a different angle, size or depth than they really are.
Assuming the swimming pool is a rectangular block, just multiply length x width x height. If these measurements are in feet, the volume will be in cubic feet.If the swimming pool has parts that are deeper than others (it is common to have a shallow part, for children who don't swim well yet), calculate the volume for each part separately, then add the results.Assuming the swimming pool is a rectangular block, just multiply length x width x height.

Sea water contains lots of dissolved salts. Thus the density of the salty sea water is more than that of water in swimming pools, and the salty water lifts you more than fresh water, which make swimming easier.
It depends where you are. The term I find most common is Gallons.
To raise the temperature of water in a thimble of water from 0 to 100 requires a small amount of thermal energy. To do the same with a swimming pool would require putting a huge amount of thermal energy into the water comparatively speaking.
64 tons or 64 000 kg or 140800 lbs 1 cubic meter of fresh water is 1000kg or 2200lbs. It actually differs slightly with elevation but this is the general rule. A swimming pool will not consist of pure water (chlorine, urine etc.) and these substances can have different densities than water so the result can vary a tiny bit.
This is because of the refraction of the light when it hits the water.
A swimming pool can appear shallower than it actually is due to the refraction of light at the water's surface. When light passes from air into water, it bends, causing objects underwater to appear closer to the surface than they actually are. Additionally, the design and color of the pool's interior can also impact how deep it appears to be.
Because the light is refracted and so the water appears shallower than it is Because the light is refracted and so the water appears shallower than it is
A diving pool is deeper than a swimming pool to ensure the safety of divers, as they need sufficient water depth to safely enter the water from heights without risk of injury. The standard depth for a diving pool is typically at least 3.5 meters (11.5 feet), allowing for safe landings from various diving heights. In contrast, swimming pools are generally shallower, as they are designed for recreational swimming and do not require the same depth for safety. This difference in depth accommodates the specific activities and safety needs associated with diving.
Let us consider an object 'O' at the bottom of a river/swimming pool. Light speeds up as it travels from water to air. So, the ray is bent away from the normal. As a result for an observer on the shore, it appears as if the rays are coming from a point 'I', which is just slightly above the bottom of the surface That is why rivers and swimming pools seem shallower than they really are.
One is not necessarily more healthy than another, because it depends on the sea and it depends on the swimming pool. Ocean conditions vary tremendously depending on the weather, currents, and other variables. When evaluating the health of a swimming pool, you need to look at how well it's maintained. A sanitized swimming pool (usually with chlorine) that is balanced (meaning pH, alkalinity, calcium hardness, etc.) is safe for swimming. If the pool hasn't been properly sanitized and balanced, swimmers are vulnerable to ear and eye infections and other problems caused by bacteria and other contaminants in the pool.
length = 20
20 ft
The width of the swimming pool is 10 ft because 10*(10+10)=200
refraction of light produces the shallow swimming pool illusion. As you look down at a pool, you are seeing light that has changed angle as it moves out of the water and into the air. Specifically, light moves faster through air than water. Light coming up from the bottom of the pool refracts down to arrive at your eyes at a shallower angle. You see the bottom of the pool a little higher and farther away than it actually is.
In theory, yes it does make a difference. However, the practical reality is that in many climates (like Texas), the pool will warm sufficiently to use without a heater for most of the year.
swimming pool = alberca (ahl-BER-kah). Some people use the word piscina, but piscina is more of a (fish) pond than a swimming pool.
