The volume of a countertop 
20080308 

From Matthew: I need to calculate volume down to cubic feet. I pour concrete countertops
and cant figure out the formula to convert inches and feet. If I have a 2.5 inch
by 2 foot by 16 foot concrete countertop how do I convert it to cubic feet
and hence know how many bags of concrete at .6 cubic feet per bag I will need.
I am trying to input the formula into a spreadsheet. thank you so much Matt Answered by Penny Nom.

From Debbie: [This article contains a special calculator to help you find the volume (for example, the cubic yards) of material required to fill (or empty) a space if you know the length, width and depth.]
We are wanting to pour a 24'x30' slab that is 5" deep. How many cubic yards of cement do we need? Answered by Penny Nom.
