Answer 1

if this is in feet then you will need 45 cubic metres to concrete this area to a depth of 6 inches (150mm)..this is standard depth for a garage floor ..you will all so need 90 tons of hardcore for a depth of 150mm so you see this is not a one man job you will need a crew ..you will all so need to do it in bays with expansion strips ..or the concrete will crack ...12 by 12 is not unreasonable ..you will need to shutter these bays
