Triangular prism calculator is used to find surface area and volume of the prism. A triangular prism is made of 2 triangles and 3 rectangles. To find the surface area we need to add areas of the 2 triangles and 3 rectangles. Volume of the triangular prime is ½ x base x height x length.
Example 1: Calculation of the surface area of the isosceles triangular prism, Length = 18, Breath = 12, Side = 5, Height = 9
For the given question
Area of rectangle
R1 = LxB = 18x12 = 216 cm2 ,
R2 =2 LxS = 2x18x5 = 180 cm2;
Area of 2 triangles =2( ½ HxB) = 2(1/2x9x12) = 108 cm2
Surface area of the isosceles triangular prism.
= R1 + 2R2 + 2(1/2HxB) =
= 216 + 180 + 108 = 504 cm2
Example 2: Calculation of the volume of the equilateral triangular prism, Length = 9, Side = 8, Height = 4
For the given question
Volume of a triangular prism = ½ x base x height x length
Since this is a equilateral triangular all the sides will be equal therefore base = side
= ½ x B x H x L
= ½ x 8 x 4 x 9
= 144 cm3
Volume of the triangular prism = 144 cm3
