Following site has been selected for construction; the first task is to establish a level pad on this site requiring excavation. The excavation has to take place in $2$ phases as the cross hatched areas of site cross sections show. Given the total area for each cross section $($top one at $5000$ sf and bottom one at $3500$ sf$,$ respond to the following questions $($length of the site is given on the aerial view and is $630$ feet$)$:

a$-$ What is the total cubic yard of soil removal for each phase?

b$-$ What is the total cubic yard for soil to be removed?

c$-$ If the factor of soil expansion is $3\%$ for this soil, what is the total cubic yard?

d$-$ How many truck with capacity of $30$ cubic yards need to be brought in to remove the soil from the site?

e$-$ If you only have the access to $10$ trucks, how many times each truck has to come and go to complete the removal from the site?

f$-$ If every truck round trip is estimated at $$1100,$ what is the total cost of the entire operation? See $2$ attached images in pdf format for the information
