Answer:
7.9 inches.
Step-by-step explanation:
We are asked to find the approximate length for converting 20 centimeters into inches.
We know that 1 inch = 2.5 centimeters.
\(\text{1 centimeter}=\frac{1}{2.54}\text{ inch}\)
\(\text{20 centimeter}=\frac{20}{2.54}\text{ inch}\)
\(\text{20 centimeter}=7.874015748\text{ inch}\approx 7.9\text{ inch}\)
Therefore, 20 centimeters are approximately 7.9 inches.
