Triangular prism

Calculate the surface of a regular triangular prism, the edges of the base are 6 cm long and the height of the prism is 15 cm.

Correct result:

S =  301.1769 cm2

Solution:

a=6 cm h=15 cm  S1=3⋅ a⋅ h=3⋅ 6⋅ 15=270 cm2 S2=34⋅ a2=34⋅ 62=9 3 cm2≐15.5885 cm2  S=S1+2⋅ S2=270+2⋅ 15.5885=301.1769 cm2
