Question

The surface area of a polyhedron can be found by

Answer 1

It can be found by summing the areas of its faces

The surface area of a polyhedron is equal to the sum of the area of all of its faces. Said another way, the surface area is the total area covered by the net of a polyhedron.

Answer 2

the surface area of a polyhedron can be found by sum of the area of all its sides.

Explanation:

The surface area is nothing find the area of each faces and add them together.

Surface area = Sum of area of each faces.

Polyhedron is a three dimensional figure.

For instance, cube a polyhedron which has 6 square faces.

Surface area of a cube =
`a^(2) + a^2 + a^2 + a^2 + a^2 + a^2 = 6a^2`, where "a" is the side of the square.

Therefore, the surface area of a polyhedron can be found by sum of the area of all its faces.
