The formula for calculating the surface area of a prism is SA 2B Ph, where B is the area of the base, P is the perimeter of the base, and h is the height of the prism. The angle of the prism does not directly affect the surface area calculation.
Formula for calculating the area of sphere is : 4 * pi * r * r
The formula for calculating the electric flux () through a closed surface is EdA, where E is the electric field and dA is a differential area element on the surface.
The formula for calculating the surface charge density of a sphere is: Q / 4r, where represents the surface charge density, Q is the total charge on the sphere, and r is the radius of the sphere.
The formula for calculating the electric flux through a surface due to a point charge is given by q / , where is the electric flux, q is the charge, and is the permittivity of free space.
The formula for calculating heat transfer by convection is: Q = h * A * ΔT, where Q is the heat transfer rate, h is the convection heat transfer coefficient, A is the surface area, and ΔT is the temperature difference between the surface and the surrounding fluid.

(2/3)*base*height
6(pi)l2, where l = length of side
A = 2 x pi x r (r + h)
It depends on how many sides are part of the "opening".
