Create a class with a main method and three other methods. In the main method, declare double variables for length, width and height of a 3D box. Implement methods for boxVolume, boxSurfaceArea, boxDiagonal. Be sure to fully comment the methods with javaDoc parameters @param and @return. In the main method print out the volume, surface area and diagonal for a given set of dimensions. You may get dimensions from user entry. Mathematical formulas for a box with length I, width w, and heighth Volume: Iwh Surface area: 21W + 21h + 2wh Diagonal: (1^2 + w 2+h^2)^(1/2)
