Step-by-step explanation:
Use formula for cube volume:
V=a³
Then add informations you already have and you are done.
V=0,5³
V=0,125 m³
 
        
                    
             
        
        
        
The total length of the steel used in the frame is 270 cm, if the decorative steel up of 6 stems and each stem is 45 cm.
Step-by-step explanation:
The given is,
            Decorative steel made from circular circle of 6 stems
            The length of the stem is 45 cm
Step:1
          We need to find the total length of the steel used in the decorative steel,
           Let,  T - Total length of the steel
                   L - Length of the stem
                   n - Number of stems used in steel frame
Step:2
        Formula to find the total length of the steel is,
                              
  ×
 × 
        From given,
                    = 45 cm
 = 45 cm
                   = 6 stems
 = 6 stems
        Substitute the values in formula,
                            ( 45 × 6 )
 ( 45 × 6 )
                               = 270
                           270 cm
 270 cm
Result:
          The total length of the steel used in the frame is 270 cm.
 
        
             
        
        
        
Answer:
5m + 4
Step-by-step explanation:
First, use the distributive property to open the parentheses.
2(2m + 2) + m = _m + 4
4m + 4 + m = _m + 4
Simplifiy:
5m + 4 
Hope this helps!
