Triangular 6345

Calculate the volume and surface of a triangular prism whose base is a right triangle with sides a = 3m, b = Va = 4m, and c = 5m. The height of the prism is v = 5.5 m.

Correct answer:

V =  33 m3
S =  78 m2

Step-by-step explanation:

a=3 m b=4 m c=5 m h=5.5 m  S1=a b/2=3 4/2=6 m2  V=S1 h=6 5.5=33 m3
o=a+b+c=3+4+5=12 m S2=o h=12 5.5=66 m2  S=2 S1+S2=2 6+66=78 m2
