Question

1. determine the surface area of each of the shipping boxes. complete the last column. note: because you are finding all sides of a rectangular prism, you can use the formula sa = 2lw + 2wh + 2lh. 3. according to your table, which shipping box requires the least material to build? 4. which shipping box requires the most material to build? 5. what do you notice about the effect of dimensions on surface area? 6. what is the cost of the cardboard for one shipping box that requires the least material? 7. what is the total cost of the cardboard for one shipping box that requires the most material? 8. what other considerations might be important to consider when shipping the boxes?

Explanation:

Since the dimensions of the shipping - boxes are not provided, we can't calculate the surface areas and costs precisely. But we can still provide a general step - by - step approach for questions 2 - 7 and a general answer for question 8.

Step1: Calculate surface area for each box

For a rectangular prism with length $l$, width $w$, and height $h$, use the formula $SA = 2lw+2wh + 2lh$. Repeat this for each box in the table (not shown here).

Step2: Compare surface areas

Arrange the calculated surface areas in ascending and descending order. The box with the smallest surface area requires the least material, and the box with the largest surface area requires the most material.

Step3: Determine cost for least - material box

If the cost per unit area of the cardboard is $C$ (not given in the problem), and the surface area of the least - material box is $SA_{min}$, then the cost of the cardboard for this box is $Cost_{min}=C\times SA_{min}$.

Step4: Determine cost for most - material box

If the surface area of the most - material box is $SA_{max}$, then the cost of the cardboard for this box is $Cost_{max}=C\times SA_{max}$.

Answer:

1. Without dimensions, we can't calculate the surface area. But use $SA = 2lw + 2wh+2lh$ for each box.
2. After calculating surface areas for all boxes, the box with the smallest surface area requires the least material.
3. After calculating surface areas for all boxes, the box with the largest surface area requires the most material.
4. Generally, larger dimensions result in a larger surface area. Also, the shape (how the dimensions are proportioned) can affect the surface area for a given volume.
5. Without knowing the cost per unit area of cardboard and the surface area of the least - material box, we can't calculate the cost. But the formula is $Cost = C\times SA_{min}$.
6. Without knowing the cost per unit area of cardboard and the surface area of the most - material box, we can't calculate the cost. But the formula is $Cost = C\times SA_{max}$.
7. Other considerations might include the strength of the box (thickness of cardboard), the volume of the box (to fit the item being shipped), ease of handling (shape and weight distribution), and environmental impact of the cardboard.
