With Cuemath, you will learn visually and be surprised by the outcomes. The formula for calculating the trapezoidal prism is: Surface Area of a Trapezoidal Prism = h (b + d) + l (a + b + c + d) square units and a height of 3. Solution: Using the Pythagoras theorem, the slant height or the non-parallel side = (16+1) = 17 = 4.123 ft, The perimeter of the base is the sum of the lengths of the sides. Thus, the simple formula for calculating the surface area of a trapezoidal prism involves the area of the base, the perimeter of the base, and the slant height of any side of the prism. A particular case is a rectangle: in this case, it is a trapezoid in which all its internal angles are right. The length of the four rectangles will be the sum of the four sides of the trapezoid, the two bases, and the other two sides. Area of a trapezoid. #S = ha +hb + al + cl + bl + dl#, 79466 views Research source If you take the average of these He has more than three years of experience writing for and working with wikiHow. Note that all measurements are of the same units. We will find the surface area of a trapezoidal prism in few steps. Step 3: Add the respective values in the formula, (a+b+c+d) H or PH, and you will get the lateral surface area of the hexagonal prism. just calculate it. . But what if you don't know the height h?
