How to find the surface area of a 3d shape? To find the surface area of a 3d shape, we need to find the area of each of the faces. To find the area of square and rectangular faces, we just need to multiply the adjacent sides together. To find the area of triangular faces, we need to multiply the base by the perpendicular height and then halve ...
