Surface Area, Lateral Area, and Volume Formulas In the table shown B is the area of the base, P is the perimeter of the base, h is the height of the object, l is the slant height of the object, r is the radius of the base if the base is a circle, C is the circumference of the base if it is a circle, S is the surface area of the object, L is the ...

Jan 17, 2010 · A right-angled triangular prism is called a right prism. The formula for calculating the volume of a prism is V = B x h, where B = area of base, and h = height of the prism. Perimeter, Area, and Volume 1. The perimeter of a polygon (or any other closed curve, such as a circle) is the distance around the outside. 2. The area of a simple, closed, planar curve is the amount of space inside. 3. The volume of a solid 3 D shape is the amount of space displaced by it.
