Answer :

The total length of the wire that is left over is (A) 1 inch.

What is the length?

  • Distance is measured by length.
  • Length is a quantity with the dimension distance in the International System of Quantities.
  • Most measurement systems select a base unit for length from which all other units are derived.
  • The meter is the base unit of length in the International System of Units.

To find the total length of the wire that is left over:

  • We know that 1 foot = 12 inches.
  • So, 1 feet = 36 inches.
  • We divide 36 by 7 and we get a remainder of 1.

Therefore, the total length of the wire that is left over is (A) 1 inch.
