Calculate the surface area of the box shown in the diagram.

How many centimeters are there in 1.56 meters?
Here the calculation is quite simple.
If one meter is equivalent to centimeters we should multiply it by to get the number of centimeters.
That is, meters equals centimeters.
Sometimes we will have to solve exercises in which we will have to convert a unit to a much smaller one. In this case we will make an intermediate calculation and go through a unit that is "in the middle".
For example, how many centimeters are there in 2 kilometers?
We know that one kilometer is equivalent to meters.
Therefore, we will first convert kilometers to meters and then meters to centimeters.
meters
meters?
We will multiply the km by :
Therefore, km equals meters.
Now we will make the conversion to centimeters.
.
centimeters?
We will multiply the m by and we get:
Therefore, km equals cm.
Another way is to multiply directly: knowing that to convert kilometers to meters you multiply by and to convert meters to centimeters you multiply by , we can multiply , that is, multiply directly by .
We recommend doing it step by step to avoid confusion :)

What is the concept of length?
Length can be defined as the part that measures an object from one side to another, that is, the distance between one point to another, the unit in the International System (SI) is meters, that is, we can measure the length of an object usually in meters, but there are also units of equivalence to this unit, such as centimeters, millimeters, hectometers, decameters and kilometers.
What are the instruments for measuring length?
There are different instruments to measure the length of an object or in other words the dimension or distance from one point to another, some of the most common instruments are the following:
What is a unit of length?
A unit of measure will be the one that we will use as a reference to measure and quantify an object, in the case of the unit of length is the meter by the International System of Units. The meter is the unit of reference most frequently used to measure the length of an object.
How many centimeters are meters?
For this exercise we must know that centimeters and meters are units of measurement that are multiples, i.e. in this case
So if a meter has centimeters, then let's make a multiplication
Then equals
How many centimeters are equal to inches?
In this case we must keep in mind that , so for this exercise let's do a multiplication
Therefore inches equals centimeters.
