5. YSTEM WIDTH,LEN�TH AND VOLUME <br /> M. elect width= 3.0 ft <br /> N. I using rock,divide bottom area by width:(H,I,J or K)divided by P=lineal feet <br /> 1320.0 ft� I 3.0 ft = 440.0 lineal feet <br /> ock depth below distribution pipe plus 0.5 foottimes boitom area: <br /> ock depth+0.5 foot x Area(H,I,J,K,L) <br /> (�ft+0.5 ft)x 1320.0 ft� = 1980.0 ft� <br /> olume in cubic yards=volume in cubic feet divided by 27 <br /> 1980.0 127= 73.3 yd3 <br /> eight of rock in tons=cubic yards times 1.4 <br /> 73.3 x 1.4= 102.7 tons <br /> 0.
