b. Find the total surface area of 100 boxes.

To find the total surface area of 100 boxes, first, determine the surface area of one box. For a rectangular box, the formula is , where , , and are the length, width, and height. Once you calculate the surface area of one box, multiply that value by 100 to get the total surface area of all boxes. Don’t forget, the dimensions must be in the same units for an accurate result!

When tackling such problems, it’s easy to get caught up in multiplying directly without verifying the formula’s application. A common mistake is forgetting to include all three dimensions in your calculations. Another tip is to double-check your calculations for any arithmetic mistakes, especially when handling multiple boxes! Making a small error can add up significantly when scaled to 100 boxes!
