First, substitute<span> the given values into the formula. Then, multiply the sum of the triangle sides by the height of the prism (H) and add the values together for the answer, </span>making<span> sure to include the appropriate unit of measurement. The answer is the surface area of the </span>above<span> triangular prism is 486 square inches.</span>
2(3x-2)=14
1) Distribute 2
(6x-4)=14
2) Add (4) one both sides
6x-4=14
6x+4=14+4
6x=18
3) Divide 6 one both sides
6x / 6 = 18 / 6
4) Solve
X=3
