It depends, but in let's look at a simple example to help you see how. How would you find the surface area of a cube. Find the surface area of one of the faces and since there are six of those, multiply it by 6. For example, a 2x2x2 cube. Each face has a surface area of 4 and there are 6 of them so the total surface area is 24 units. We do the same thing with other 3d objects, but it may be harder to find the surface area of faces. In face, sometimes there are no faces and we may need calculus to find the surface area.

How do you find the surface area of square?
if a 2d object, height x width. if a 3d object, height x width x 6.
What is the difference between surface area and radius?
surface area is the area of a 3D object radius is half of the diameter of a circle
How does a 2D shape look different from a 3D shape?
A 2D shape is flat and only has a surface area whereas a 3D shape is an object that has surface area and volume.
How do you find the surface area of a 3d trapezoid?
You find the surface area of each of its six faces and add them together.
How does surface area different from area?
Surface area is the area of all the sides of a 3D object, but area could be anything. e.g. Area is the surface of a 2D object or if you say the area of all the sides, it means the same as Surface area. -----=-----=-----=-----=-----=-----=-----=-----=-----=-----=-----=-----=-----=-----= By Austin from Covenant Christian School
