WebDifferent types of calculations related to a prism: The formula for calculating the area and volume of a prism is as follows- Area of a Prism Area= 2 × A + P × h Where A is the area of the base, P is the perimeter of the base, And h is the height of the prism. Volume of a prism V = A × h Where V is the volume A is the area of the base
