this week in math 10, i learned how to find the surface area of a triangular prism and also all the unit conversions. unit conversions are the thing you need to know most for this unit so it is very important, it tells you the formula you use to convert one measurment into another. to find the surface area of a triangular prism you first find the sum of the area of all the sides, this involves using Pythagorean Theorem and multiplying, the formula for finding the surface area of a triangular prism is 2 times b time height divided by two plus legth time width times legth time width time legth time width then you fill in the spots with the correct numbers and do the equation, then you have your answer.
