Answer: To find out how many one cubic yard sacks of cement must be ordered, you simply divide the total amount of cement needed (9.83 cubic yards) by the volume of each sack (1 cubic yard per sack):
Number of sacks = Total cement needed / Volume per sack
Number of sacks = 9.83 cubic yards / 1 cubic yard per sack
Number of sacks = 9.83 sacks
So, you would need to order approximately 9.83 one cubic yard sacks of cement for the concrete pour. Since you can't order a fraction of a sack, you might need to round up to the nearest whole number depending on how the cement is packaged and sold.
