How many sq ft does a 90 pound bag of concrete cover | A 90lb bag of concrete coverage at 2″ thick | A 90lb bag of concrete coverage at 4″ thick | how much area does a 90lb bag of concrete cover.

Concrete ready mix made of blended mix of Portland cement, sand gravel and other approved ingredient, generally, dry ready mix concrete are available in different bag size and weight condition such as 40lb, 50lb, 60lb bag, 80lb bag and 90lb bag.

Weight of Ready mix concrete in dry condition is about 133 lbs per cubic foot which is approximately equal as 3600 lbs per cubic yard, or 2136 kg per cubic meter. The weight of concrete is determined by its density, which can vary based on the amount of aggregate, water, and air in the mix.

In United States, based on Imperial measurement system, 1 cubic yard is unit of measurement of volume represented by 3 feet long by 3 feet wide by 3 feet depth such as 3’×3’×3′ = 27 cubic feet, so 1 cubic yard is equal to 27 cubic feet.

Quikrete or Sakrete 90 lb bag of concrete mix can be used for building or repairing foundation walls, sidewalks, curbs, steps and ramps and for setting posts. Quikrete 90 lb sack concrete mix is ideal for both structural and non structural applications over 2 inches.

In this article we know about how many sq ft does a 90 pound bag of concrete cover, and how many square feet in a 90 pound bag of concrete.

**Yields of a 90lb bag of concrete**

A 90 pound sack or bag of concrete yields volume about 0.676 cubic feet, which is approximately equal as 0.025 cubic yards.

To calculate cubic feet in a 90lb bag of concrete, divide 90 pound by 133 lb (weight of 1 cubic foot concrete mix) = 90/ 133 = 0.676 cubic feet.

To calculate cubic yards in a 90lb bag of concrete, divide 90 pound by 3600 lb (weight of 1 cubic yard concrete mix) = 90/ 3600 = 0.025 cubic yards.

**How many sq ft does a 90 pound bag of concrete cover**

A 90 pound sack or bag of concrete is approximately 0.676 of a cubic foot. If you are pouring a 4 inch slab it would cover approximately 2 square feet. It will take just 40 sacks or bags to make a cubic yard of concrete which covers about 81 square feet at 4 inch thickness.

A 90 pound bag of concrete, 2″ thick, will cover 4 square feet. A 90-pound bag of concrete, 4″ thick, will cover 2 square feet. A 90 pound bag of concrete, 6″ thick, will cover 1.5 square feet.

To calculate how many square feet does a 90 pound bag of concrete cover, convert thickness in feet, divide yields of 0.676 cubic feet of 90lb bag of concrete by thickness of slab in feet to get coverage of an 90lb bag of concrete in square feet.

**Coverage of a 90lb concrete at 2″ thick**

● Thickness in feet = 2/12 = 0.166 feet

● Coverage = 0.676/ 0.166 = 4 square feet

**Coverage of a 90lb concrete at 3″ thick**

● Thickness in feet = 3/12 = 0.25 feet

● Coverage = 0.676/ 0.25 = 2.7 square feet

**Coverage of a 90lb concrete at 4″ thick**

● Thickness in feet = 4/12 = 0.33 feet

● Coverage = 0.676/ 0.33 = 2 square feet

**Coverage of a 90lb concrete at 6″ thick**

● Thickness in feet = 6/12 = 0.5 feet

● Coverage = 0.676/ 0.5 = 1.5 square feet
