Answer:
200cm cubed
Step-by-step explanation:
Remember that volume of a rectangular prism is length x width x height
 
        
                    
             
        
        
        
Ratios don't have to be "per" something, while rates are "per" something. 
Ratios compare 2 or more values, as well as rates. 
        
             
        
        
        
Answer: each width = 10, each length = 21
Explanation: from the question we know that L=2w + 1 and we also know that a rectangle has the perimeter of 62 when we plug it in the equation we will get 62= 2(2w+1+w) we will multiply the 2 now and we will get 62=4w+2+2w we will combine like terms and we will minus two from both sides ending up with 60=6w we will divide six from both sides and we will get w=10 then we will use l=2w+1 to find the length and it will be 21
        
             
        
        
        
21in.
1/2*base*height=area of a triangle
Side^4=square area
Square+Triangle(4)=total
Square=9      Triangle=3
