The surface area formula for a cube is 6 x side2, as seen in the figure below: This calculation requires only one measurement, due to the symmetricity of the cube. side2is the surface … See more

The surface area formula for a rectangular box is 2 x (height x width + width x length + height x length), as seen in the figure below: Since a rectangular box or tank has opposite si… See more

The surface area formula for a cylinder is π x diameter x (diameter / 2 + height), where (diameter / 2) is the radius of the base (d = 2 x r), so another way to write it is π x radius x 2 … See more

The surface area formula for a sphere is 4 x π x (diameter / 2)2, where (diameter / 2) is the radius of the sphere (d = 2 x r), so another way to write it is 4 x π x radius2. Visual on t… See more
