To find the area of a box, you need to calculate the total surface area of all its faces. A box has six faces, each with its own area. To find the total area, you would add up the areas of each face. The formula for the surface area of a box is 2lw + 2lh + 2wh, where l is the length, w is the width, and h is the height of the box.

The question is ambiguous. I can determine the outside area of a closed box, given its height H, width W and depth D. The top and bottom are equal area, D x W. The front and back are equal area, H x W. The right and left sides are equal, H x D. So, we have 2 x (DW+HW+HD) = total outside area. If all sides are equal, we have 6xL^2, where L is the length of one of the sides.

Do you mean the surface area of the box? If so... What you do is break the surface area into 6 rectangles: Two rectangles have sides of length 6.3 and 12.6 inches. Two rectangles have sides of length 6.3 and 4.2 inches. Two rectangles have sides of length 12.6 and 4.2 inches. Find the area of each of the six rectangles (using the standard formula for the area of a rectangle, A = W x H), and add up all six. The sum of the areas of the six rectangles will be the surface area of the box. Since the lengths of the sides are in inches, the area will already be in square inches, and therefore you don't have to "turn it into square inches".
Lets say its 12 inches by 5 inches by 10 inches It will be 12X5 = 60X10 =600square inches.
The highest and lowest numbers in a box and whisker plot are shown by the two dots at the end of the "whiskers". To find the range, you must subtract the highest number from the lowest number.
The surface area is 1,385.4 cm2
