An icosahedron is a body enclosed by 20 triangles. The total surface area is the sum of the areas of the individual triangles. In the case of a regular icosahedron, it is of course 20 times the surface area of any of the triangles - i.e., 5 times the square root of 3 times a2, where "a" is the length of one of the sides.
The area of each face is Length2*sqrt(3)/4 So total surface area = 20*Length2*sqrt(3)/4= 125*sqrt(3) = 216.51 square units.
The total surface area! The total surface area! The total surface area! The total surface area!
It is called "the total surface area".

The total surface area is about 754 ft2
That is the definition of the surface area!
Find the area of each face separately and then add them together for the total surface area.
You need to find the area of each of its faces and add them together. An icosahedron may or may not have parallel faces. For example, an icosahedron, in the form of a pyramid with a 19-gon base will have no parallel faces.
Total surface area is 176 units2
the total surface area of a cubic centimetre
(surface area of cube 1 or 2 (either)) times 2 = (total surface area of two identical cubes)
Total surface area = (2*pi*radius2)+(pi*diameter*height)
