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
How do you find the surface of a 3D object?
on a 3D object to find the surface is to look on all flat surfaces. yourwelcome
What is the difference between surface area and area?
Area is usually pertaining to the area of a 2d object but surface is 3d object
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.
How is the surface area different from the area?
The surface area is the area of every face of a 3D object, such as a cube or sphere. Area usually refers to a flat object, such as a circle or rectangle.
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 surface area different area?
surface area is basically the total area of each surface of the 3d object. Sa = 2-D A = 3-D

What does it mean to find the area of a shape?
To find the the area of a shape is to find the space that is enclosed within a 2D object. Do not mix it up with volume, which is the space enclosed within a 3D object.
How do you find the surface area of a 3D triangle?
Sum the areas of all four faces.
Perimeter of a 3D shape?
A "perimeter" is a 2D measurement and cannot be applied to a 3D object. However, sometimes the area around a building or piece of property to be protected is known as a perimeter. In that case, measure the sides of the facet of the object facing the ground, add them up and you have a perimeter. "Surface area" would be the closest thing to a perimeter, purely speaking. Measure the area of one facet of an regular 3D object (such as a cube), multiply that number by the number of facets, and you get the surface area.
