The table shows how some lengths in inches are related to their equivalent lengths in centimeters.

The table titled inches verses centimeters has 2 inches for 5.08 centimeters, 5 inches for 12.7 centimeters, 10 inches for 25.4 centimeters, 25 inches for 63.5 centimeters, and 30 inches for unknown centimeters marked in question mark.

What number is missing from the last row of the table?

1 answer

To find the length in centimeters equivalent to 30 inches, we can use the conversion factor between inches and centimeters. The relationship is given by:

1 inch = 2.54 centimeters.

Using this conversion, we can calculate the length in centimeters for 30 inches as follows:

\[ 30 \text{ inches} \times 2.54 \text{ centimeters/inch} = 76.2 \text{ centimeters} \]

Therefore, the missing number in the last row of the table for 30 inches is 76.2 centimeters.
