A: each 90-pound bag of quikrete® concrete mix will yield approximately 0.675 cubic feet when mixed.

## 90 Lb Bag of Concrete Is How Many Cubic Feet?

A 90 lb bag of concrete is equal to approximately 0.45 cubic feet. This is because one cubic foot of concrete weighs about 200 lbs, so a 90 lb bag of concrete would be equal to half of a cubic foot. This can be a tricky calculation, as concrete is usually sold in bags of different sizes and weights.

When using concrete, it is important to measure the amount you need accurately. If you use too much, you may end up with a weak finished product that is prone to cracks and other issues. Too little can result in a finished product that crumbles easily.

In order to calculate how many cubic feet of concrete are in a 90 lb bag, you will need to know the weight of the bag and the density of the concrete. The weight of the bag is typically printed on the bag itself. The density of the concrete is usually listed on the side of the bag.

Once you have the weight and density of the bag, you can then divide the weight by the density to determine the number of cubic feet in the bag. For example, if the weight of the bag is 90 lbs and the density is 80 lbs per cubic foot, then you can divide 90 by 80 to get 1.125 cubic feet.
