if you want the outside area just calculate the area of one face of the cube H x L and multiply by six. double this amount if you want the internal surfaces added to this such as if you had a cardboard box.

The surface area of a box, which is a cuboid, depends on its length, width and height. A cube is a special type of cuboid in which the length , width and height are all the same.
You find cubic inches in a box by multiplying its length by its width, and by its height. The measurements for length, width, and height should all be in inches. This is known as the volume of the box.
Multiply 5 x 3 x2=30 inches. I don't agree, 5inX3inX2in=30 CUBIC inches and is the volume of the box. Square inches is a measure of area and the question is meaningless unless you are asking for the surface area of the box or a side of the box.
Add all the area of six faces of the box in gerneral the surface area of a cube shape box is 6a2 and of cuboid is 2(lb x bh x hl)
The question is somewhat puzzling. The surface area of a box is not sufficient information to determine its shape and, therefore, its size. Furthermore, surface area would not be given as 480 cubic inches since that is not a measure of area (but of volume). On the other hand, if the box has a volume of 480 cubic inches, the answer, becomes trivial. 480 inch cubes = 480 cubic inches. Rocket science!
measure the sides of the box
It should be relatively easy to find the surface area of a box when you are given the surface area.
"each side is 10 12 inches" Unsure about how this is worded, however: To find the area of a cube, you must multiply the area of one face, by its length. The surface area for a cubic box with 10" sides would be 10x10x10 = 1000 For a box of 12" sides, this would be 12x12x12 = 1452
find the area of each side and add them together.

no; surface area applies to the square unit of measurement of a 2-dimensional surface, such as one face of a box (length and width). Volume is a 3-dimensional representation that takes the 2-dimensional surface area (length x width) and adds a 3rd dimension in the form of depth, or height. Answers in volume will always be a cubic unit of measure. Summing it up: Surface Area: L x W Cubic Area (Volume): L x W x H
The surface area of a box, which is a cuboid, depends on its length, width and height. A cube is a special type of cuboid in which the length , width and height are all the same.
Presuming its a cube, then: 6 * ( ( cube root ( 343 ) )2 ) > = 294 sq cms
To find the box with the least surface area for a given volume, you can start by using the formula for the surface area of a rectangular box: ( SA = 2(lw + lh + wh) ), where ( l ), ( w ), and ( h ) are the box's length, width, and height. Given a specific volume ( V = lwh ), you can express one dimension in terms of the others and then use calculus to minimize the surface area function. Typically, the optimal box shape with the least surface area for a fixed volume is a cube, as all sides are equal. You can confirm this by applying the method of Lagrange multipliers or analyzing the critical points of the surface area equation.
The formula will depend on what it is that you are trying to find: the volume or the surface area.
Volume is how much an object can store - like how much can you put inside a box. Surface area is the sum of the area of an objects surfaces - such as if you have a box, find the area of one side. Then you just multiply it by 6 (because a box have 6 faces) to get the total area of an object's surface.
