Question

A carpenter needs to cut a 5-foot, 8-inch piece of wood form an 8-foot board to make a repair to a door. How many inches of wood will he have left after he makes the cut and repairs the door

Answer 1

The left over wood in foot is 2.34 foot

or 2 foot 4 inch

Explanation:

This problem desires to test our unit conversion skills

Step one: let us work with foot and convert inches to foot.

The total wood is 8 foot, and we are expected to subtract 5 foot 8 inches from it.

converting 8 inches to foot we have

1 inch -----0.0833333 foot

8 inch-----x foot

cross multiplying we have

x= 8*0.0833333

x= 0.66 foot

Hence the total number of wood to be subtracted in foot is 5.66 foot

i.e 8-5.66= 2.34 foot

The left over wood in foot is 2.34 foot

or 2 foot 4 inch
