How do you calculate concrete in a cylinder?
The base area of a concrete cylinder is equal to its volume divided by its height. Say a concrete cylinder has a volume of 340 cubic inches and a height of 12 inches. Its area will then be 340 in³ / 12 in = 28.33 in² .
How much concrete is in an 8 sonotube?
How much concrete does it take to fill a 10 inch sonotube?
Based on the fixed diameter and depth (or height) of the sono tubes for a project, our customers can get an accurate calculation of the amount of ready-mix concrete needed to fill that sono tube. For example, a sono tube with a 10″ diameter and a 4′ depth requires 0.08 cubic yards of concrete.
What size sonotube for a deck?
A good size for a common backyard deck is a 10″ or 12″ diameter for the sonotube and a 20″ base diameter. Of course, you can get a 24″ base size and it will spread weight over an even greater surface area. The one down side to this is the extra digging involved.
How do you calculate concrete volume?
For concrete, the formula for volume is as follows: length x width x thickness….Here’s what the math looks like for a 10′ by 10′ concrete patio:
- 10 x 10 = 100 square feet.
- 4 ÷ 12 = .33.
- 100 x .33 = 33 cubic feet.
- 33 x .037 = 1.22 cubic yards.
How do you calculate concrete in a circle?
Two methods for calculating the area of a circle
- You can do the pi*r2 method, where pi = 3.141592…, r = the radius of the circle, and squared is squared.
- Or, you can shortcut to a ratio: a circle within a square box occupies 78.5% of the space.
How much concrete do I need for a deck post?
You’d be shocked at how many bags of concrete mix you’d have to mix by hand to fill a form tube. Figure concrete volume by multiplying the height of the post and column in feet by the radius of the tube in feet squared times 3.14. Divide the total by 27 to get the cubic yardage you need to order.

How do you calculate volume of steel in concrete?
Calculate Steel quantity in slab as 1% of volume of concrete = 0.01× 7850× 1= 78.50kg:- according to using Thumb Rule Steel quantity required for RCC slab should be 1% of total volume of concrete, here steel density = 7850 kg/m3, so quantity of steel in 1m3 of concrete slab = 0.01× 7850× 1= 78.50kg, so, therefore 78.50 …
How do you calculate footing volume?
Example Footing Calculation
- Volume = H/3 (A1+A2+(√A1 x A2)
- A1 = 2 x 1.5 = 3 Sqm.
- A2 = 0.5 x 0.3 = 0.15 Sqm.
- H = 0.15m.
- Now Volume = 0.15/3 x (3+0.15+(√3 x 0.15)
- = 0.05 x (3.15+0.67)
- = 0.19 m3
- Volume (V) = 0.19 m3
