Aload of bauxite has a density of 3.11 . if the mass of the load is 220. metric tons, how many dump trucks, each with a capacity of 11 cubic yards, will be needed to haul the whole load? (express your answer as an integer.)

Answer : The number of dump trucks required are, 8

Explanation : Given,

Density of load of bauxite =

Mass of load = 220 metric tons =

conversions used : 1 metric ton = 1000000 g

First w have to calculate the volume of load of bauxite.

Convert cubic centimeter to cubic yard:

So,

Volume of load =

Volume of load = 92.47 cubic yards

Now we have to calculate the number of dump trucks.

Capacity of a dump truck = 11 cubic yard

Number of trump trucks required =

Thus, the number of dump trucks required are, 8
