There are approximately 27 cubic feet in a cubic yard, and an 80-pound bag of concrete typically yields about 0.6 cubic feet. Therefore, to fill one cubic yard, you would need about 45 bags of 80-pound concrete.
If you wish to get cement it's better to buy it bagged. If you wish to make concrete using the ratio suggested there would be 64 sand to 80 of gravel.
well concrete mix is a 1/3 gravel , 1/3 sand and 1/3 portland cement . I hope this helps.

This cannot be answered without knowing the width and depth.
It is 50 pounds
If using a square shovel usually about 10.
The answer is 35 lbs of gravel. 140=x+3x....where x is the lbs of gravel and 3x is the lbs of cement. Therefore 140=4x....140/4=35....so x=35

This all depends on the mix you want. I assume you mean cement when you mention the 80lb bag of concrete. I have pushed concrete in my day... Bag cement mix is the same as concrete. Don't be funny. How many 80 pound bags will make 1 yard of concrete? I want a definitive answer this time.
Typically, one 50-pound bag of concrete is needed per fence post.
To answer this question we must first differentiate between concrete and cement. Concrete is the finished product when cement is used. Analogous to bread is the finished product when flour is used. Got it? As to how many cups in a pound of powder, consider that there are 16 ounces to the pound, and eight ounces to a cup. That makes it two cups to the pound of cement. How much concrete that would make is another matter.
Less than one.
a yard of concrete can weigh from 2000 to 3500 lbs. The weight difference is because of the water, sand, and gravel mixture being different for different types of concrete.
