There is no way to find perimeter from a 3D figure. However, you can find the perimeter of a side of a triangular prism by using perimeter formulas for a parallelogram or triangle.
The lateral area [L] of a right prism with base perimeter [P] and height [h] is L=Ph.
The lateral area [L] of a right prism with base perimeter [P] and height [h] is L=Ph.

okay, to find the base of a triangular prism you just b = 2a/h (base = 2 * area/height)
When you say surface of a prism this means the total amount of space on the outside of the prism. You have specified it to be a triangular prism, but taking the surface area of all prisms is the same process for all prisms. When finding the surface area of a prism you always use this equation... S.A. = (2 x Area of Prism Base) + (Height x Perimeter of Prism Base) In a triangular prism the base would be a triangle. Therefore to find the area you have to do 0.5 x base of the triangle x height of the triangle. For the perimeter of the triangle just add the length of all the sides together. The height indicated in your S.A. = ... formula... is how tall the prism actually stands. So since this prism is a triangular prism take the general surface area equation and put the correct triangular measurements into the general equation and you have this... S.A. = [2 x 0.5 x (height) x (base)] + [Height x perimeter] Here is the formula in word form. The surface area of a triangular prism is equal to two multiplied by one half multiplied by the height of the traingular height multiplied by the triangular base compute this number and then add it to the product of the height of the prism times the perimeter of the triangular base.
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.
12 the base times the height
12 the base times the height
To find the volume of a triangular prism, find the area of one of the triangles (base of the prism) first (base x height divided by 2). When you have the area of the triangle, then multiply the area of the triangle by the height of the prism, *not the height of the base.
2*area of triangular faces + perimeter of triangle*length of prism (not prisim).
