The surface area of a three-dimension object is the total area of its surface that is exposed on the outside while its volume is the space inside the shape. For the purpose of comparison of the Volume to Surface area for the three shapes, we can assume the total surface area for each shape to be 38 cm2. This is derived from the assumption of an average size of a cube has a side length of approximately 2.5 centimeters (cm)
