WebExample 1: Find the surface area of the right triangular prism shown below. Solution: Given, base (b) = 5 units, in this case, S 1 and base is the same, the height of the triangle (h) = 12 units, length of a prism = 11 units, and the hypotenuse of the right triangle = 13 units. The surface area of a right triangular prism = bh + (S 1 + S 2 + h)L. On substituting the values, … WebFor a right-angled triangle, the base and the perpendicular height are interchangeable. ...
