Surface Area of a Triangular Prism Worksheets

Before setting off on a journey into this assortment of printable worksheets, it’s necessary to know the relation between the net and surface area of a solid. Visualize the net of a triangular prism made of three rectangles and two congruent triangles. If you add the area of these five shapes using their respective formulas, you’ll end up in the surface area. Simply put, the surface area of a 3d figure is nothing but the area of its net. Implement this fact and find the surface areas of the prisms with bases in the shapes of equilateral, isosceles, scalene, and right triangles in these pdf worksheets, ideal for students of grade 6 through high school. Get off to a flying start with our free worksheet!
