![]() ![]() CmSurface area of cuboid = Sum of areas of all six facesSurface area of cuboid = 96 + 96 + 32 + 32 + 48 + 48Surface area of cuboid = 96 + 96 + 32 + 32 + 48 + 48Surface area of cuboid = 352 sq.ĬmAlternative method:We can use the formula given below to find surface area of cuboid.Surface area of cuboid = 2(lh + wh + lw)Here, l = 12 cm, w = 4 cm and h = 8 cm.Surface area of cuboid = 2(12x8 + 4x8 + 12x4)Surface area of cuboid = 2(96 + 32 + 48)Surface area of cuboid = 2(176)Surface area of cuboid = 352 sq.cmLet us look at the next problem on 'Surface area of prism and pyramid worksheet'Problem 2:Find the surface area of the cube given below. CmArea of the back face = 8 x 12 = 96 sq.cmArea of the left side face = 4 x 8 = 32 sq.cmArea of the right side face = 4 x 8 = 32 sq.cmArea of the top portion = 4 x 12 = 48 sq.cmArea of the base = 4 x 12 = 48 sq. ![]() So we can use area of rectangle formula to get area of each face.Area of the front face = 8 x 12 = 96 sq. Solution:Surface area of cuboid = Sum of areas of all six facesIn cuboid, each face is a rectangle.
