Triangular prism

A regular triangular prism is a geometric figure whose base is an equilateral triangle.
Triangular prism surface area formula Triangular prism surface area formula where a is the side of the base, h is the height of the prism

Solution:
S =
6·a·h+a2·√3
2
=
6·11·40+112·√3
2
=
2640+121·1.732
2
=
2640+209.572
