TOTAL SURFACE AREA OF A
TRIANGULAR PRISM
WHAT IS A TRIANGULAR PRISM?
Triangular prism is a three dimensional figure with
two triangular bases and three rectangular lateral
faces.
CONSTRUCTION.
AREA OF THE BASES(TRIANGLES)=
SQRT(S(S-A)(S-B)(S-C))
where a,b,c are the sides of the triangle and s = (a+b+c)/2.
AREA OF THE LATERAL FACES =AH+BH+CH.
Where
-‘ah’ is the area of the rectangular face with breadth ‘a’ and height ‘h’.
-’bh’ is the area of the rectangular face with breadth ‘b’ and height ‘h’.
-’ch’ is the area of the rectangular face with breadth ‘c’ and height ‘h’.
TOTAL SURFACE AREA= BASE AREA+ LATERAL SURFACE AREA.
=(a+b+c)h+2(s(s-a)(s-b)(s-c))
