A cuboid is a 3-dimensional object with six rectangular faces. All its angles are right angles and opposite faces are equal. A cuboid is also called a rectangular prism or a rectangular solid.
In a cuboid, the length, width and height may be of different lengths. A cube is a special case of a cuboid in which all six faces are squares.
To calculate the surface area of the cuboid we need to first calculate the area of each face and the add up all the areas to get the total surface area.
Total area of top and bottom surfaces is lw + lw = 2lw
Total area of front and back surfaces is lh + lh = 2lh
Total area of the two side surfaces is wh + wh = 2wh
Surface area of cuboid = 2lw + 2lh + 2wh = 2(lw+ lh + wh)
