There are different formulas for different shapes, so I'll provide you with a few common ones.
Cylinder Sides: Pi x diameter x height
Top/bottom: Pi x radius squared
Cone Sides: Pi x radius x slant
Top/bottom: Pi x radius squared
Sphere: Pi x radius squared x 4
Pyramid (square base) Sides: Slant x Base x 2
Top/Bottom: Base squared
Rectangular Prism
L x W + W x H + H x L=____x2
(Rectangular Solid)

∙ 15y agoSurface area formulas are different for each shape.
square or rectangle - length*width
cube - 6*x^2 where x is the length of any given side
rectangular prism - 2ab+2bc+2ac where a, b and c are the lengths of 3 sides
circle - Pi*r^2 where r is the radius
sphere - 4*Pi*r^2 where r is the radius
cylinder - 2(Pi*r^2)+(2*Pi*r)h where r is the radius and h is the height of the cylinder
There are alot more, but these are some of the most common ones I've had to use for various reasons. A quick Google search should give you any others that you may need.

Why rough surface of a catalyst is more effective?
Rough surfaces form irregular surface increase the surface area. Catalytic action is directly proportional to the area of contact.
Why is the lining of the intestine rough?
Lining of your intestine is not smooth. Nature has adapted various methods to increase the surface area of the intestine. The surface has become grossly uneven due to this factor. The surface area of the small intestine is about 2750 square feet. That is why the surface becomes rough, although the lining is made of very soft epithelium.
What is Plutos surface area?
The temperature range of Pluto is 33 degrees Kelvin to 55 degrees Kelvin.
What are volume and surface area?
Area the measure of the two - dimensional space enclosed in a shape while volume is the measure of the three - dimensional space in enclosed in a shape. this is true said blue waffle man.Area has two dimensions. Volume has three. Also are is a measure of a surface and Volume is a space occupied by a gas or liquid.Volume is measured in cubic units and area is measured in square units.Area is surface measurement. Volume is measurement of the surface area x depth or height (think of capacity to describe volume).
How can you obtain the cells ratio of surface area to volume?
If the cell has a simple geometric shape, there are formulae that can be used. Otherwise you need to measure the surface area and the volume.
What are all factors affecting frictional force?
Mass, the bearing surface (how much weight on what surface area), and a "coefficient of friction", a measure of how rough or smooth the surface is.
What area has ribosomes on the surface?
The Rough Endoplasmic Reticulum (Rough ER) has ribosomes on its surface.
Why rough surface of a catalyst is more effective?
Rough surfaces form irregular surface increase the surface area. Catalytic action is directly proportional to the area of contact.
What instrument measures surface area?
Try a tape measure and a calculator to measure surface area.
What is The measure of an objects surface?
surface area
How does surface area affect friction?
more rough surface more friction object have
A measure of the size of a surface or a region is its?
The size of a surface or region is its area.
What does surface area?
surface area is the measure of a 3dementional and 2 dementional object
What is the measure of how much surface an object has?
Area is the measure of how much surface an object has.
What are the Similarities between area and surface area?
you can measure them
How do I determine the surface area of a baseball?
Measure its diameter.The surface area of a sphere is [ pi D2 ] .
What is the unit of measure use in area and surface area?
This depends on what unit you are using to measure in. However, area will always be measure in (unit)^2.
