The total area of all the faces of a three-dimensional object.
A six-sided polyhedron with all sides the same length.
A six-sided polyhedron with three pairs of parallel faces, all of which are rectangles.
Surface area = 6s^2 **where s is the side length of the cube.
Surface area = 2lw + 2lh + 2wh **where l, w, and h are the length, width, and height of the prism.
Surface area = 6s^2 = 6 * 5^2 = 150 cm^2
Surface area = 2lw + 2lh + 2wh = 2 * 10 * 5 + 2 * 10 * 3 + 2 * 5 * 3 = 100 + 60 + 30 = 190 cm^2
