Question

1. (referring to the last question) calculate the cost at lowes and home depot for the necessary quantity of ¾ inch 4 x 8 sheets of fiberboard (osb) panels to cover the roof. 4 pts. 19. predict the environmental advantage of making and using oriented strand boards (osb). support your prediction with evidence based on how it is made. 2 pts.

Explanation:

1. For question 18:

• Since the area of the roof and the cost - per - sheet at Lowes and Home Depot are not given, we cannot perform the actual calculation. However, the general steps would be:

Step1: Determine roof area

First, find the area of the roof to be covered. Let the area of the roof be \(A\) square feet.

Step2: Determine area of one panel

The area of a \(4\times8\) sheet is \(A_{panel}=4\times8 = 32\) square feet.

Step3: Calculate number of panels

The number of panels \(n=\frac{A}{A_{panel}}\) (round up to the next whole number if \(n\) is not an integer).

Step4: Calculate cost at Lowes

Let the cost per panel at Lowes be \(C_{L}\). The total cost at Lowes \(T_{L}=n\times C_{L}\).

Step5: Calculate cost at Home Depot

Let the cost per panel at Home Depot be \(C_{H}\). The total cost at Home Depot \(T_{H}=n\times C_{H}\).

OSB is made from wood strands which are often from fast - growing trees or wood waste. This reduces the need for harvesting old - growth forests. Also, the manufacturing process can be energy - efficient and the product is recyclable.

Answer:

Without values for roof area and cost - per - panel, we cannot give a numerical answer.
