64 feet squared because 4 cubes
        
                    
             
        
        
        
We can use the Pythagorean theorum
a^2+b^2=c^2
c^2 is the length of the longest side squared
so 
6^2 + b^2 = 10^2
36+ b^2 = 100
-36               -36
b^2 = 64
b = 8
b is the same thing as your "x", so x = 8

440...marked down by 30% means u pay 70%
70% of 440 = 0.70(440) = 308
308 ..marked down by 10% means u pay 90%
90% of 308 = 0.90(308) = 277.20 <== price after markdowns
