find the surface area of one of the faces (all of the faces are the same if it is a true cube) for example if the length is 2 and the width is 2 then u multiply that and get the surface area of that then since there is 6 faces to a cube so u multiply the surface area of one of the faces by 6
faces every polyhedron has one
The faces are the flat, triangle-shaped surfaces that make up the surface of the pyramid. A pyramid has four faces.
2 Faces ( 1 Base and 1 Curved surface )
Normally a cube has 6 flat surface faces
