Convert kilometers (km) to square kilometers (km2)

It is impossible to convert a square kilometer directly to a linear kilometer directly, but such a problem often arises in various calculations. The given situation is a great example. You only need to approach it differently, not by converting square kilometers, but by finding the area of ​​the rectangle that this street represents. That is, multiply one side of the rectangle street by the other.

 

1.5 sqm x 800 sqm = 12000 square meters = 0.012 square kilometers. Well, then, knowing the concrete consumption per 1 square kilometer, we find how many times 100 square meters are laid in the total area:

 

12000/100 = 120 times. Now it is easy to find the volume of concrete:

 

120 x 3 tons = 360 tons of concrete will be required by builders for 0.012 square kilometers.

 

The problem to convert sq km to km and km to sq km requires a non-standard approach. This unique method, instead of directly converting units, invites us to imagine a square kilometer as the area of ​​​​a rectangle and measure it along its perimeter. To do this, we multiply one side of the rectangle by the other. This approach allows us to determine the area of ​​the street in square kilometers as if we were measuring a sheet of land by running along its borders.

 

Converting km to km2, we use the square method. A square kilometer is the area of ​​a square with a side of one kilometer. Therefore, 1.65 kilometers will be equal to approximately 2.7225 square kilometers.

 

A kilometer and a square kilometer are incompatible concepts. Area does not translate into length, just as length does not translate into area. Any attempt to do so is nonsense, no matter what the conditions of the arithmetic problems are.

 

Area can only be calculated using some necessary lengths. However, lengths cannot be calculated based on a location.

 

One square kilometer can be:

• A square with sides 1:1. This km to km2 calculator makes it.
• A rectangle with sides 0.5:2; 0.25:4; 0.1:10; and so on, ad infinitum.
• Any geometric flat figure (except a circle and various "semicircles").

 

So again ... When solving this problem, you need to follow a clear and structured process: for clarity, schematically draw this street on a sheet of paper 0.8 km long and 0.015 km wide, and indicate the dimensions.

 

Action 1: Find the street's area using the formula length (0.800 km) multiplied by width (0.015 km): 0.800 * 0.015 = 0.012 square kilometers.

 

Action 2. Ask yourself: If 3 tons of concrete were used for 100 square meters, then how much would be needed for 0.12 square kilometers? After all, 0.12 sq km is clearly more than 100 square meters. How many times? To answer this question, you need to divide 12,000 by 100. We get 120. 120 times more concrete will be needed!!!

 

The final action is straightforward: 3 tons of concrete multiplied by 120 equals 360 tons of concrete that will be needed to cover the street.
