Answer:
216
Step-by-step explanation:
The formula of finding the surface is length * width * height or LxWxH.
Since everything is 6 you just multiply 6*6*6 which gives you 36*6 which gets you 216. You don't need the top 6 just to find the surface she will paint. 
Hope this helps!
 
        
             
        
        
        
Total cost=$142
cost of parts=$62
cost paid for labour=$142-$62=$80
According to question, 
》cost of labour per hr=$32
which can be written as,
》cost of labour/time=$32
Use cross multiplication,
》time=cost of labour/32
Since cost of labour is 80,
Time=80/32
 =2.5hrs
