The Surface area of a cuboid with length 10 cm breadth 10 cm and height 9 cm is 560 cm².

What is the surface area?

A cuboid is a three-dimensional figure bounded by six rectangular planes, having a different magnitude of length, width and height. If you look around and you can see a box, brick or anything in the shape of a rectangle, it could be cuboid.

Here, length of cuboid is 10 cm

         breadth of cuboid is 10 cm

         and height of cuboid is 9 cm

Surface Area of Cuboid = 2 (lb + bh + lh)

                                         = 2 (10X10 + 10X9 + 10X9)

                                        = 2 (100 + 90 + 90)

                                        = 2 X 280

Surface Area of Cuboid = 560 cm²

Thus, the Surface area of a cuboid with length 10 cm breadth 10 cm and height 9 cm is 560 cm².
