A wire that is 48 centimeters long is shown below.

The wire is cut into two pieces, and each piece is bent and formed into the shape of a square.

The sides of the square measure 6 cm

Step-by-step explanation:

If we cut the wire in half, we have to:

48/2 = 24

We would have two 24 cm wires

With each wire a square will be formed, therefore the question I suppose must be how much each side of the square measures.

We know that the square has 4 equal sides, therefore:

4/24 = 6

The sides of the square measure 6 cm

reduce the friction between its moving parts

step-by-step explanation:

in fact, by reducing the friction between the moving parts of the machine, it is possible to reduce the energy wasted due to this friction; therefore, more input energy is converted into useful work, and this will improve the efficiency of the machine.
