D(7, 3), E(8, 1), and  F(4, -1)
We calculate the squared distances between the points:



Since  we have a right triangle with hypotenuse DF.
 we have a right triangle with hypotenuse DF.
 
        
             
        
        
        
The dimensions of the carton are:
10 x 10 x 10 [inch OR unit cubes - it's the same since cubes' dimensions are 1 x 1 x 1 inch)
