How many cubic inches in a bag of concrete

The number of cubic inches in a bag of concrete depends on the size of the bag and the density of the concrete mix. Typically, a standard 80-pound bag of concrete mix yields about 0.6 cubic feet, which is equal to 1,175 cubic inches. Therefore, an 80-pound bag of concrete mix contains approximately 1,175 cubic inches of material.

There are concrete bags from brands like Quikrete or Sakrete that weigh around 90 pounds (90lb), 80 pounds (80lb), 60 pounds (60lb), 50 pounds (50lb), and 40 pounds (40lb). A premix bag of concrete is blended mix of Portland cement, sand and gravel with some additives.

To calculate the yields of a bag of concrete in cubic inches, you need to divide the weight of a bag of concrete by 133 to get cubic feet (because a bag concrete weighs about 133 pounds per cubic foot), and then your cubic feet multiply with 1,728 to get cubic inches of concrete.

Here’s are general guideline for how many cubic inches in a bag of concrete:-

1. A 90 lb bag of concrete mix yields roughly 1,175 cubic inches of concrete mix (since (90/133) × 1,728 = 1,175 cubic inches).
2. A 80 lb bag of concrete mix yields roughly 1,037 cubic inches of concrete mix (since (80/133) × 1,728 = 1,037 cubic inches).
3. A 60 lb bag of concrete mix yields roughly 778 cubic inches of concrete mix (since (60/133) × 1,728 = 778 cubic inches).
4. A 50 lb bag of concrete mix yields roughly 648 cubic inches of concrete mix (since (50/133) × 1,728 = 648 cubic inches).
5. A 40 lb bag of concrete mix yields roughly 519 cubic inches of concrete mix (since (40/133) × 1,728 = 519 cubic inches).

Here’s are the table for how many cubic inches in a bag of concrete:-

In general, there would be approximately 1,175 cubic inches in a 90 lb bag of concrete, 1,037 cubic inches in a 80 lb bag, 778 cubic inches in a 60 lb bag, 648 cubic inches in a 50 lb bag, and 519 cubic inches in a 40 lb bag of concrete.
