Calculating Surface Area and Volume

The video tutorial addresses a real-world problem involving the calculation of surface area. Miss B needs to determine how many rolls of brown paper are required to wrap 75 shoeboxes. The tutorial walks through the steps of calculating the surface area of one shoebox, then multiplying it by the number of boxes to find the total surface area needed. It also calculates the surface area of one roll of paper and determines the number of rolls required by dividing the total surface area by the area of one roll. The solution concludes with the recommendation to purchase two rolls to ensure there is enough paper.

What is the main problem Miss B is trying to solve in the video?
