## How much concrete do I need calculator?

**How to calculate concrete**:

**Determine**how thick**you want**the**concrete**.**Measure**the length and width that**you**‘d like to cover.- Multiply the length by the width to
**determine**square footage. - Convert the thickness from inches to feet.
- Multiply the thickness in feet by the square footage to
**determine**cubic feet.

## How much quikrete do I need calculator?

Assume a 10-by-10-foot square area with **concrete** 4 inches thick. When you multiply 10 by 10 by. 333 feet, you get 33.333 cubic feet. Divide the total cubic feet **needed** by the total cubic feet that can be made from one bag of **Quikrete Concrete** Mix.

## What is the formula for calculating concrete?

**Calculating** the volume for **concrete** requires using three dimensions: length times width (which is area) times the height (thickness) or L x W x H. If you are using feet as your standard unit of measurement, this **formula** will give you the volume of **concrete** in cubic feet.

## How many bags of concrete do I need for a 10×20 slab?

A 60-pound **bag** yields. 017 cubic yards, and an 80-pound **bag** yields. 022 cubic yards. For a 10 x 10 **slab**, you **would need** 77 60-pound **bags** or 60 80-pound **bags**.

## How many square feet does a yard of concrete cover at 4 inches thick?

One Cubic Yard of Concrete: 4-inches thick – covers **81 square feet**. 5-inches thick – covers 65 square feet.

## How many cubic meters is a 25kg bag of concrete?

**Concrete** is a mix, typically of 1 part **cement** to 4-5 aggregate, and a **cubic metre** of finished **concrete** weighs around 2.5 tonnes, so requires around 500kg **cement** or 20× **25kg bags**. In direct answer, there is about 1/100th or 0.01 **m3** in a **25kg bag**.

## Can you pour concrete directly on dirt?
