Calculate how many liters in 1 cube of water

What is water, everyone knows. This is the same fluid that flows from our tap, which we drink, which we wash and use for cooking. It is filled with lakes, seas and oceans, it is contained in the soil, under the earth and in the heavens. Spilled on the ground in the form of rain in the warm season, and in winter covers the entire earth in the form of snow and ice. And the man himself is almost eighty percent of the same water. Even school children in the school know that the chemical formula of water is read as H2O ("two oh"), and even know that H is hydrogen, and O chemists understand oxygen.

how many liters in 1 cube of water

Without water on our planet can not existno living organism. Ecologists frighten us by the fact that most of the water on the planet is not suitable for drinking, as it contains a large number of dissolved salts - sea and ocean water. And the reserves of fresh water are currently about 80,000 cubic kilometers. Is it a lot or a little? Let's see how much it will be in cubic meters and in liters, that is, we will find out how many liters are in 1 cube of water, since, strictly speaking, a cubic kilometer is not a system unit. One cubic kilometer contains one billion cubic meters.

The figures are impressive, is not it? There are many more waters on our planet. But how much is it in more liters habitual to us? After all, we never measure water with cubic meters, we measure the volumes of liquids in liters. So, let's figure out how many liters in one cube of water. Let's start with the title.how many in 1 cube of litersOne cubic meter is a cube withsides equal to one meter. Let's build such a cube. If we pour a liter of water into this cube, for example, from a regular liter jar or a measuring cup, then it will cover only the bottom of this cube. And the answer to the question: "How many in a cube of liters?" - we can get it only if we fill this cube to the top.

It is clear that running around with a liter jar from the tapnobody wants to cube. Therefore, you can use a bucket or just build a smaller cube. We all know how to count and know exactly what is easiest to divide by 10. So let's build a cube with a side in the decimeter. Our jar filled this cube to the top! Hooray!

how many liters of water in one cubeNow you can calculate how muchliters of water in one cube. If one liter is equal to one cubic decimeter, then you just need to calculate how many of these cubic decimeters are in cubic meters. If you take a square, you can calculate quickly - there they are exactly 100, that is 10 in the second degree. But we do not have a square, but a cube. Consequently, how many liters in 1 cube of water? That's right, exactly 1000.

You would have had the tenacity to run 1000 times sinceliter jar? I doubt it. And mathematics, more precisely, even arithmetic, helped dispense with just one campaign for water. Now we know exactly how many liters are in 1 cube of water. It remains only to translate cubic meters into cubic kilometers, and one can calculate what the fresh water reserves on our planet are.

Another interesting fact is thatone liter of clean water (distilled) under normal conditions weighs exactly one kilogram. So now, knowing how many liters in 1 cube of water, we can calculate the total weight of fresh water on the planet. And if you want to know the total weight of water in all the seas and oceans, you will have to take into account that the density of salt water is higher than fresh water, and therefore a liter of salt water should be more.
