CAUTION: Values obtained from the above tables are for only the one TRIANGLE of the orom-section under consideration. Corrections for tenths of feet in width and height may be made by considering the numbers on the table from 1 to 9 as tenths and taking one tenth the values found in the tables. For example,to find the number of cubic yards when Width-W-16.2 and Height-H-5.3,opposite 16 in "Width"column and under 5 in the"Height" column read 1.18. To correct for additional 0.2 foot of width,opposite 2 in the"Width" column and under 5 in the"Height"column read 0.18 and correct to.018. To correct for additional 0.3 foot in height, under 3 in "Height" column and opposite 16 in "Width"column read 0.89 and correct to.0139. Therefore,the total cubic yards in the given TRIANGLE for a depth of 1 foot-1,48+.018+.089-1.587 or approximately 150 cu.yda.per 100 feet. If width exceeds 40 feet,use one half real width and multiply result by 2. If both width and height are larger than values given on table use one half of each value and multiply result by 4. 16 1 . i
