Solve for the volume of concrete pavement, convert 6 SOLUTION inches to meter = .15 m. (see table 1-1) 1. Find the volume of the concrete slab; V = Thickness x Width x Length V - = Thickness x Width x Length V = .15 x 6.00 x 1,000 m. V = .25 x 7.20 x 1,000 meters V = 900 cubic meters V = 1,800 cubic meters 2.
