Answer:
Total amount of material would be ⇒ 5 square feet
Explanation:
~ The amount of material is, simple put, the surface area of the boxes. Knowing that, let us calculate the area of each surface of the first net, for simplicity: 0.5 * 1 = 0.5 ft^2, 0.5 * 2 = 1 ft^2, 1 * 2 = 2 ft^2. Now two of these area are congruent to another surface, such that the amount of material needed for the first net is 0.5 * 2 + 1 * 2 + 2 = 1 + 2 + 2 = 5 feet^2.
Knowing that amount of material for each net is 5 ft^2, the total amount of material would be ⇒ 5 feet^2
