Convert the mixed number to inches. 3 feet 8 inches = 44 inches (12 inches per foot x 3 feet= 36 inches + 8 inches= 44 inches). 44 inches (length each section needs to be) x 4 (number of sections needed)=176 inches (total molding needed). To determine the amount of molding needed in feet, convert 176 inches into feet by dividing 176 inches by 12 inches. You get 14 2/3 feet, so the shortest board length is 15 feet.
There is total 12 inches in one feet. The length of the board man must buy is equal to 14 feet.
There is total 12 inches in one feet.
Given information-
The total number of section has to be cut is 3.
The length of each section is 4 feet 8 inches.
There is total 12 inches in one feet. Thus the number of inches in 4 feet is,
[tex]\rm in=4\times12\\\rm in=48[/tex]
Thus the total inches in the 4 feet is 48.
The length of each section is 4 feet 8 inches. The total inches in the 4 feet and 8 inches is,
[tex]\rm in=48+8\\\rm in=56[/tex]
Thus the length of each section is 56 inches.
Now the total 3 section 56 inches required from a whole board. Thus the board should 3 times the 56 inches.
Suppose the length of the board is x. Thus,
[tex]x=56\tiems3\\x=168[/tex]
Thus the length of the board is 168 inches. Convert this into the feet by dividing with number 12.
[tex]x=\dfrac{168}{12} \\x=14[/tex]
Hence the length of the board man must buy is equal to 14 feet.
