a building contractor is to dig a foundation 36 ft long 12 ft wide and 9 ft deep the contractor pays $20 per load for trucks to remove the dirt each truck holds 9 cubic yards what is the cost to the contractor to have all the dirt hauled away?

Ithink if ur looking for a ratio it would be 12: 3

Planet earth has a mass of 5.9726x10²⁴ kg.then: 5.9726x10²⁴ kg=100% of the total earth mass.if the water´s mass=5x10-4 % of the total mass, we can solve this problem by the rule of three.5.9726x10²⁴ %*10⁻⁴ %x=(5.9726x10²³ kg)(5*10⁻⁴  %) / 100 %=2.9863x10¹⁹ kganswer:   the mass of the planet´s water would be   2.9863 x 10¹⁹ kg.

and surely you know how much that is.
