We can use ratios to solve
152 dollars     532 dollars
---------------- = ----------------
4 days              x days
Using cross products
152x = 4*532
152x =2128
Divide each side by 152
152x/152 = 2128/152
x =14

1 inch        2/3 inches
------------ = ----------------
 6.5 ft          x ft
Using cross products
1x = 2/3 * 6.5
x = 4.333333
c = 4 1/3 ft
 
        
                    
             
        
        
        
The answer is 5.5 m.
Cube
Volume = length x width x height
Since the length, width and the height are the same in cube, the formula can be: 
Volume = length^3
Let x metres be the side length of the cube.
166 = x^3
x = ∛166
x = 5.495864.....
x = 5.5 (nearest tenth)
