Detailed explanation-1: -Most standard pencils are 19 centimeters, or 7.5 inches, before they are sharpened.

Detailed explanation-2: -a standard pencil of 7.5 inches in length, is zero point one nine meters long, which is 19 cm.

Detailed explanation-3: -How Long Is A Sharpened Pencil? After the first sharpening, most standard pencils will measure 7 inches (18 cm) long.

Detailed explanation-4: -A standard, hexagonal, “#2 pencil” is cut to a hexagonal height of 1⁄4-inch (6 mm), but the outer diameter is slightly larger (about 9⁄32-inch (7 mm)) A standard, #2, hexagonal pencil is 19 cm (7.5 in) long.

Detailed explanation-5: -Since the pencil starts at 1 cm and ends at 19 cm, you might be tempted to report the length as 18 cm, but that would be wrong! Remember, a ruler like this is precise enough to be reported to the hundredths of a centimeter. Thus, the correct answer for the length of the pencil is 18.00 cm.
