Explanation
The formula to calculate the area of a triangle is 1/2 * base * height. In this question, the area is given as 8 square inches and the base is given as 6 inches. By rearranging the formula, we can solve for the height. 8 = 1/2 * 6 * height. By dividing both sides of the equation by 3, we get 8/3 = height. Therefore, the height of the triangle is 8/3 inches.
