How many Pieces of wood would be required and the number of pieces you actually need for the finishing?

Question

Finishing the Quad Seating

The Quad area has a new section on the full length of one side.
The top of he seating is to have a wood finish which is o go to the full length of 26 meters.
The piece wood you have is the size of the wood to be used.The length of this wood is 850mm.

You have been asked to estimate the numbers of pieces of wood that will be required and then calculate the number of pieces you actually need for the finishing. 

Answer 1

First, we must realize that we are given two different units of measurements. In order to solve this problem, we must convert completely to millimeters(mm) or meters(m). Here, I have converted to meters (m):

850mmX(1m/1000mm)=0.85m

Now, we ask how many of these 0.85 meters is necessary to reach the total length of 26 meters that the problem requires?:

Let x=how many pieces needed

(0.85)(x)=26

x=26/0.85

x=30.58823529

Answer Part 1: Therefore, for the "how many pieces are needed," we would say 30.58823529 pieces (if your teacher does not want you to round this answer).

Answer Part 2: Since the problem states that, "the piece of wood you have is the size of the wood to be used," we need to note that the total number of pieces of wood you would need is 31 (because we are rounding 30.58823529 to the nearest whole number to find out how many total whole pieces of wood you need to complete the project.)
