The length of the strip is 12 cm, divide it by bending it into 4 equal parts; the length of one fourth strip is 3 cm. How to find out the length of the entire strip.

Dividing the strip, we see that it now consists of four parts. If we know the length of one part (this is 1/4 of the entire strip, which is 3 cm), then we need to multiply it by the number of parts we have obtained (that is, by four parts).

3 cm * 4 pieces = 12 centimeters.

Or add all four parts of the strip:

3 + 3 + 3 + 3 = 12 centimeters.

So we find out that the length of the entire strip will be equal to 12 centimeters.
