Find the surface area or the volume for each of the triangular prisms. Each worksheet has answers on the second page. These area and volume worksheets are common core standards for geometry for middle school grades.
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!

Surface Area of Triangular Prisms | Integers
Make an all-out effort and keep 6th grade and 7th grade students au fait with finding the surface area of triangular prisms! Sum up the areas of three rectangular faces and two triangular bases to arrive at the surface area.
Surface Area of Triangular Prisms | Decimals
Plug the decimal dimensions in SA = bh + (s1 + s2 + s3)H, where ‘b’ and ‘h’ are the base length and height of the triangle; ‘s1’, ‘s2’, and ‘s3’ are the lengths of three sides of the triangle; ‘H’ the prism's height, and find the surface area.
Finding the Height and Surface Area
Apply the Pythagorean theorem and figure out the height of the triangular base; find the base area using the height; add up twice this area to the sum of the areas of the rectangular faces and determine the surface area of prisms.
