The net created in Part B can help Leonora's family determine the amount of plastic they will need to wrap around each hay bale by providing them with the surface area of each bale that needs to be covered. The net represents the three-dimensional shape of the hay bale, so by calculating the surface area of the net, the family can determine the amount of plastic needed to cover the hay bale.
To calculate the surface area of the hay bale, the family can use the dimensions of the net created in Part B. They can measure the length and width of the net and then multiply those dimensions to find the surface area. This will give them an accurate estimate of the amount of plastic they will need to cover each hay bale.
By using the net to determine the surface area of each hay bale, Leonora's family can ensure that they have enough plastic to cover all of their hay bales. This can help to prevent spoilage and ensure that the hay remains fresh and usable for a longer period of time. Additionally, by accurately estimating the amount of plastic needed, the family can save money by not purchasing more plastic than necessary.
