The surface area of the cube=6a^2, a is the side of the cube.
The surface area of cuboid=2(lb+bh+hl), where l, b, h are the cuboid’s length, breadth and height.
The surface area of cylinder=2(pi)r(r+h), r is the radius of the circular base and h is the height of the cylinder.
The volume of Cube= a^3, a is the side of the cube.
The Volume of cuboid=lbh, where l, b, h are the cuboid’s length, breadth and height.
The Volume of the cylinder=(pi)(r^2)h, r is the radius of the circular base and h is the height of the cylinder.
