we have
3400 cubic feet
We need to transform the cubic feet into cubic yards in order to know how many truckloads we need
1 cubic feet = 0.037037 cubic yards
3400 cubic feet = 125.9 cubic yards
then we dived the 125.9 between 14 cubic yards in order to obtain the number of truckloads we need
125.9/14=8.99
we round to the nearest whole number
the nearest whole number is 9
we will need 9 truckloads
