The correct answer is C. I just took a test and answered B but that is not the correct answer. it is actually C
Answer: 9 pieces
Explanation: Divide 8 by 7/8 to find the number of cut pieces and you'll get 9.
It’s 90 after you multiply the length, width, and height
let the consecutive multiples be 7(n-1) , 7n and 7(n+1)
so 7(n-1)+7n+7(n+1)=777
or 3n=111,
n=37
