The surface area of a rectangular prism is the total area or region covered by its six faces. If l, b, and h are the dimensions of a rectangular prism, then the formula for its surface area is 2 (lb + bh + hl).
We know that a cube has six faces; therefore, the total surface area of the cube will be equal to the sum of all six faces of the cube. Also, we can observe from the shape of a cube that the surface of the cube is in a square shape. Therefore, the area of each face of the ...
