allen is building birdhouses that require 12-ft-long boards. how many pieces that are exactly 12ft long can be made from a board that is 814ft long?

67 boards

Step-by-step explanation:

Given :

Total board length = 814 ft

Each board must be exactly 12 feet

Number of 12 ft boards which can be cut from 814 feet,

= 814 ÷ 12

= 67.83 boards

But because the question requires boards which are exactly 12 feet long, so we have to round down to the nearest whole number

hence 67.83 boards rounded down to the nearest whole board becomes 67 boards.

554.4
