length x width x height
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.
find the area of each side and add them together.
sa=2lw+2lh+2wh
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.
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.
you multiply the length times width times height.
to calculate the area of the front surface of a box you should
Measure the height and multiply it by the width.
to know how much paint is needed to coat it
The surface area of a box is the sum of the areas of the individual faces. If that's what you said, then there is no difference.
