CAUTION: Values obtained from the above tables are for only <br /> the one TRINGLE of the cross-section under consideration. <br /> Corrections for tenths of feet in width and height may be made by considering the <br /> numbers on the table from 1 to 9"tenths and talrine one tenth the values found <br /> in the tables. For esampl• to find the number of cubic yards when Width-W-16.2 <br /> and Height-H-5.8, opposite 16 in"Width"column and under 5 in the"Hsight" <br /> oolumn read 1.18. To correct for additional 0.2 foot of width,opposite 2 in the"Width" <br /> column and under Din the"Height"column read 0.18 and correct to.018. To correct <br /> for additional 0.8 foot inht, under 8 in "Height" column and opposite 16 in <br /> "Width"column read 0.89 and correct to.089. Therefore,the total cubic yards in the <br /> ven TRIANGLE for a depth of 1 foot-1.48+.018+.089-1.587 or approximately <br /> lb0 cu.yde.per 100 feet. <br /> If width exceeds 40 feet,use one half real width and multiply result by 2: If both <br /> width and heigbt are larger than values given on table use one half of each value <br /> and multiply result by 4. <br /> i t <br /> 16 <br /> t <br /> J <br /> 4 <br />
