Triangular prism

Calculate the volume and surface area of a triangular prism if it is given:
a = 6.8 dm. ..Va = 4 dm. (base edge length and base triangle height length) ... ... .v = 23 dm (body height)

Correct answer:

V =  312.8 dm3
S =  496.4 dm2

Step-by-step explanation:

a=6.8 dm v1=4 dm v2=23 dm  S1=a v1/2=6.8 4/2=568=13.6 dm2 V=S1 v2=13.6 23=312.8 dm3
S2=(a+a+a) v2=(6.8+6.8+6.8) 23=52346=469.2 dm2 S=2 S1+S2=2 13.6+469.2=496.4 dm2
