Is the 6m x 450mm x 300mm one side of the strip foundation and the 4.5m x 450 x 300mm one end. if so the calculation is 6 x 0.450 x 0.300 x 2 = 1.215 cubic metres of concrete. 4.5 x 0.450 x 0.300 x 2 = 1.62 cubic metres of concrete. 1.215 + 1.62 = 2.835 cubic metres of concrete required for all 4 sides of the foundation. Get onto a ready mix company and ask for 3 cubic metres of concrete your job specification should tell what type of mix you need. Good luck Terry owen
