## How do you figure square yards of concrete?

**How do I calculate how much concrete I need for a slab?**

**Measure**the area in feet.- Multiply length by width, and then by thickness.
- Divide the resulting number by 27 to find cubic
**yards**.

## What is the concrete formula?

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 do I work out how much concrete I need?

Next, you **need** to determine square footage – do this by multiplying the length by the width. Convert the thickness from inches to feet. Then, multiply the thickness (in feet) by the square footage to determine cubic feet. Next, you **need** to convert cubic feet into yards – do this by multiplying it by 0.37.

## How much concrete do I need for a 10×10 slab?

For a **10 x 10 slab**, we’d suggest a mix with a capacity of about 4,000 pounds per square inch, or psi. This is basic for residential projects, and it can withstand traffic and support heavy loads.

## How many bags of cement do I need for 100 square feet?

Ans.:- 7.6 no of **cement bags** (381.30 kgs) are required for **100 sq ft** rcc roof slab 4 inch thick m20 grade concrete. Ans.:- 7.6 **bags** (381.30 kgs), 9.5 **bags** (476.10 kgs) & 11.4 **bags** ( 570.8 kgs) **cement** are required for **100 sq ft** rcc roof slab 4 inch, 5inch & 6 inch thick respectively in m20 grade of concrete.

## How do you calculate 1m3 of concrete?

Thus, the quantity of **cement** required for 1 cubic meter of **concrete** = 0.98/0.1345 = 7.29 bags of **cement**. The quantities of materials for 1 **m3 of concrete** production can be calculated as follows: The weight of **cement** required = 7.29 x 50 = 364.5 kg. Weight of fine aggregate (sand) = 1.5 x 364.5 = 546.75 kg.

## How much does 30 yards of concrete cost?

Use $90 per cubic **yard** as a ballpark figure for **concrete prices**, but **concrete** slab **cost** will vary by region. Also, expect a fee of about $60 per load for delivery from a **concrete** truck for **concrete cost**. There could be other fees for such things as Saturday **concrete** truck delivery and small loads.

## How thick should a concrete driveway be?

As for thickness, non-reinforced pavement four **inches** thick is standard for passenger car driveways. For heavier vehicles, a thickness of five **inches** is recommended. To eliminate standing water, the driveway should be sloped towards the street a minimum of one percent, or 1/8 **inch** per foot, for proper drainage.
