Divide by the number of faces. For example, divide by 6 if it is a cube. Divide by 4 if it is a triangular pyramid.
Find the area of each face separately and then add them together for the total surface area.
Find the area of each face and add them all up.
... face and add them together.
Find the surface area of each individual face and then add them together to give the total surface area of the pyramid.

Find the area of each face separately and then add them together for the total surface area.
Find the surface area of each face then add them together to give the total surface area.
Determine the area of one face (2m x 2m = 42m). Multiply by the number of faces on a cube - 6. So, 6 x 42m = 242m total surface area.
Determine the area of one face (2m x 2m = 42m). Multiply by the number of faces on a cube - 6. So, 6 x 42m = 242m total surface area.
You will need to find the surface area of each face and add them together.
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.
If its a triangular based pyramid (tetrahedron) then it will have 4 equilateral triangle faces and so find the area of one face and multiply it by 4 to give the total surface area.
Each face has a surface area of 3 x 3.As there are 6 faces, the total surface area is 6 x 3 x 3 = 54 square metres
Find the area of each face and add them all up.
You find the area of each face and add the results together.
... face and add them together.
Total surface area = (2*pi*radius2)+(diameter*pi*height)
