The surface area of a polyhedron can be calculated by first calculating the area of each of its polygonal surfaces and adding these together.
The surface area of some curved solids (sphere, cylinder, cone) can be calculated from formula but for most curved solids are more complicated and require integration.

What solid shape minimises surface area?
the sphere has the smallest surface area for any given volume.
Formula to work out the surface area of any object?
Calculus can be used to find the surface area of any object given that you know the equation describing said object. It's usually easier to find the area from experiment or through using a combination of existing models to approximate the surface area
To find the surface area of the three dimensional figure you must find the perimeter of a face and then multiply by the height?
NO. This is the way to get the volume of a prism, not the surface area of any three-dimensional figure. To find the surface area of a three-dimensional figure, you must find the area of each of its faces and then add the side-areas together.
To calculate the surface area of any polyhedron you find the area of the base and then multiply that value by the number of faces?
False
