you maltiply the length by the wedth
the proper way to calculate internal area
lenght x the avg width. get three widths and aveg them than mutiply them time the lenght.
You need to:* Calculate the surface area * Calculate the volume * Divide the surface area by the volume
to calculate the area of the front surface of a box you should
surface area divided by volume
The small intestine needs a large internal surface area because that is how it absorbs the nutrients in food.
To calculate the surface area of a shape find the area of each side, and then, add all of the areas together. The sum of the areas is the surface area.
The idea is to (1) calculate the surface area, (2) calculate the volume, (3) divide the first by the second.
You measure or calculate the surface area; you measure or calculate the volume and then you divide the first by the second. The surface areas and volumes will, obviously, depend on the shape.
The surface area of a sphere = 4*pi*radius2
It depends on the shape whose surface area you are interested in.
Area = Length * Breadth.
Depends on the figure you're trying to calculate
The same way you calculate the surface area of any other rectangle: Multiply the length of the wall by its height.
