### How do you measure the surface of a triangular prism?

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.
