The soil borrow material to be used to construct a highway embankment has a mass unit weight of $98\mathrm{.}0$ pcf$,$ a water content of $6\%,$ and the specific gravity of soil solids is $2\mathrm{.}65.$ The specifications require the soil be compacted to a dry unit weight of $112$ lb per cf and the water content be held to $13\%(279,355$ bcy$,21\mathrm{.}0$ gal$/$bcy borrow, $18\%,132\mathrm{.}1$ lb$/$cf$).$

a$.$ How many cubic yards of borrow are required to construct an embankment having a $230,600$ cy net section volume?

b$.$ How many gallons of water must be added to the borrow material, on a per cubic yard basis, assuming no loss by evaporation? Please show all work and steps neatly for a better understnding Thank you
