Answer:
The height of the big cone is double the one in the small cone 
h2 = 2h1 
Step-by-step explanation:
Given that: 
- The volume of the small cone: 5 cubic inches
- The volume of the big cone: 10 cubic inches 
As we know, the volume of a cone is as following: 
V = (1/3)*area of the base*height 
If the base diameter are unchanged => area of the base of the two cones are  unchanged and from the given information, the volume of the big cone is double the volume of the small cone. So the height of the big cone is double the one in the small cone 
<=> h2 = 2h1 
 
        
             
        
        
        
To find area you do length x width. To find perimeter you do length + width.
