To find the surface area of an equilateral triangular prism you take the area of the rectangular sides and the triangular bases and add them up and your done.


Surface area of the triangle x the length of the prism.


Assume that a = apothem length of the triangular prism, b = base length of the triangular prism, and h = height of the triangular prism. The formulas to find the surface area is SA = ab + 3bh.


The lateral area [L] of a right prism with base perimeter [P] and height [h] is L=Ph.


It depends on the size of the triangular prism, but depending on the side of the prism you use the triangle area formula to find it or the rectangle area formula to find it.


2*area of triangular faces + perimeter of triangle*length of prism (not prisim).


You find the area of each of the four triangular faces of the prism and add them together.


You look at the edge of the triangular prism and count the points


you calculate the area of one side, then multiply it by three.


A triangular prism has 5 sides. Three are rectangles and two are triangles. If you fold the net out flat you can get the dimensions and find the surface area. Each rectangle is length by width. And the triangles should be congruent and remember are length times height divided by two.


It is important to remember the formulas when learn Geometry. The surface area formula for a triangular prism is A=2A(subscript B)+(a+b+c)h.


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.


You have to find the areas of each individual triangle's area and add them all up together.


Work out the area of each of the 5 nets and then add them together


The surface area of a rectangular prism is the sum of the length times the width of its three pairs of faces. A triangular wedge is half of that.


Find the area of a triangular section, 1/2bh, and then multiply by the length of the prism.


Capacity generally implies volume in geometry. To calculate the volume of a triangular prism, find the area of one of its triangular bases and multiply it by the height of the shape.


okay, to find the base of a triangular prism you just b = 2a/h (base = 2 * area/height)


Just use the formula (Base x Height '/. 2) to get the area


Find the surface area of the top or bottom face and multiply that by the depth of the prism. For example, a triangular prism would have a volume of (1/2 * base * height) * (depth)


Two of them are equal and the third is not.Calculate the areas of each face and add them together.


find the area of all the faces then add them all up. this is how you get surface area and there isn't any formula for it



The volume of any prism is worked out in the same way whether it's a hexagonal prism, circular prism or a triangular prism. You just need to times the length of the prism against the area of the cross-section.


All the faces of a triangular prism must be flat. So finding them should not be too difficult!
