Density p mass m volume V The density of concrete is 315 gcm 3 while the density of aggregate will vary by the type of stone used. Square and Rectangular Areas The volume for a rectangular space is equal to the length times the width times the height. The concrete cubic yards formula is a formula of volume and as such requires three dimensions.
For example- if youve got a wall thats 5 high 8 wide and 10 feet long youd have 5x0667334then 334 x 10 334then 33427 123 cu yds.
4027 148 cubic yards of concrete For pouring concrete footings 20 feet long 2 feet wide and 1 foot long you would need 148 yards of concrete. Follow the steps below to calculate the total number of cubic yards required. Multiply 008 x 50 4 total cubic yards of concrete for 50 tubes. The formula for concrete calculations is length x width x depth divided by 27.
