Surface area and volume are calculated for any three-dimensional geometrical shape. Ratio of the areas of the shapes is the same as ratio of the arc length to the circumference. In this article we will explore the surface area formula of various objects with different shapes. Prism Surface Area Formula and Prism Volume Formula A prism is a geometric shape consisting of a stack of identical base shapes stacked on top of each other to a depth d.
