Square Area Formula A = a2 A = a × a a = edge length Rectangle Area Formula A = l × w l = length w = width Border Area Formula A = (l1 × w1) - (l2 × w2) l1 = outer length w1 = outer width l2 = inner length w2 = inner width Trapezoid Area Formula A = 1/2(a + b)h a = base a b = base bSurface area is the sum of the areas ofall faces (or surfaces) on a 3D shape. A cuboid has 6rectangular faces. To find the surface area of a cuboid, addthe areas of all 6 faces. We can also label the length (l),width (w), and height (h) of the prism and use the formula,SA=2lw+2lh+2hw, to find the surface area.
