How the measurements and cost are calculated
Length Required = Length + (2 x Maximum Depth) + (2) (Edging Needed)
Width Required = Width + (2 x Maximum Depth) + (2) (Edging Needed)
Length x Width is the Total Area.
To Calculate the Cost
For example, if thickness of 0.5mm costs KSH 200/- Per Square Metre.
Length x Width x Thickness (200/-)
