How many baths of paint does it take to cover 10km of road markings?

10 km = 10000mAssuming 2 (x_m) markings (depending on the students knowledge of roads) on either side of road each marking 10cm (w_m) wideeach marking with a paint thickness of 5mm (t_m) each marking 10km (L_m) longAnd hence an approximate answer is obtained for the volume of paint required.
Next step is to calculate the number of Baths required. Assuming:a bath tub 1.2 m (L_b) long, 1m (w_b) in width and height (h_b), thickness (t_b)And hence a volume of the fluid a bath can contain can be calculated, and from it the number of bath tubs filled with paint required to paint 10kms of road markings can be acquired.
