To calculate the surface area of a truncated pyramid, you first take the surface area of each side. That would be the base time the straight height. If it is a 4 side pyramid with equivelant sides, multiply that answer by 4.
A "formula" is some mathematical rule for calculating something you wish to know. So "the formula of the rectangle-base pyramid" will be some expression which tells you something that you want to know about it. Beyond that there is no way anyone can tell you, since you do not say what feature of the pyramid you are thinking about (height, volume, surface area, weight...).
A = 2 x pi x r (r + h)
the formula for calculating the surface area of an oval is A = Pi * a * b where a & b are the semimajor(half the long) and semiminor(half the short) axes

The answer will depend on what information you have.

It depends on how many sides are part of the "opening".
A = 2 x pi x r (r + h)
2(l*w)+2(w*h)+2(l*h)=surface area
Surface area is the total space that a three-dimensional object occupies. When using the mathematical formula for its shape you get the surface area measurement.
