To find the SA of any prism, find the area of each face. (*Note: Depending on the shape of the face, there might be different formulas.
Area of Square=length x length
Area of Triangle=base x height divided by 2
Area of Trapezoid=A1+A2 (divide the trapezoid into two triangles and find the area of each triangle, then add them) )
After you find the areas of all the faces of the prism, add all the areas to get the SA.

Assuming you mean a rectangular prism, you get the smallest surface area if the prism is a cube. You can calculate the required length of side to get that volume; then, based on that, the corresponding surface area.
you calculate the area of one side, then multiply it by three.
Please be specific: Are you referring to surface area, volume? the length of one side?
Calculate the area of each net individually and then add them all up together
To calculate the surface area of a triangular prism, you need to find the area of the two triangular bases and the three rectangular faces. The formula for the surface area of a triangular 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. Given the bases are 4 cm^2 each and the sides are 10 cm^2, you would first find the perimeter of the base (P = 2s + b) and then calculate the surface area using the formula provided.
