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 cm215.5885 cm2  S=S1+2 S2=270+2 15.5885=301.1769 cm2
