Question

what is the surface area of a triangle prism

Answer 1

where is the picture and the measurements?

Answer 2

well you should be able to calculate yourself anyway, just make sure you calculate the area of each face and add it all together

Answer 3

so it would be the total area of the two triangle faces and three rectangles add together

Answer 4

from there it should be easy, the area of triangle if you have forgotten is (1/2)base x height and for a rectangle it's length x width
