Since the order matters, it's a permutation of 7 letters, but mind you in 
MOROCCO. you have 3 O's and 2 C's, Hence the arrangements are:
⁷P₇ /(3!2!) = 7!/(3!2!) = 5040/(3!2!) = 420 arrangements

Answer: 2w + 4 = 35
Step-by-step explanation:
Carl's two checked bags and his one backpack together weigh 35kg. 
Carl's two checked bags have equal weight so both their weight can be denoted as 2w.
Equation is;
2w + 4 = 35
If you were to solve;
2w + 4 = 35
2w = 35 - 4
w = 31/2
w = 15.5kg
 
        
             
        
        
        
Volume of one cubic block = (1/6)^3  = 1/216 cu ins
Volume of the prism = 1/3 * 2/3 * 2/3  = 4/27  cu ins
Number of blocks to fill prism  = 4/27 / 1/216   = (216*4) / 27  =  32
