CAUTION: Values obtained from the above tables aro for only the one TRIANGLE of the ororssotion under oonsidemtion. Corrections for tenths of feet in width andi ht may be made b7 the numbers on the table from 1 to 9 as tenths and taidoy one tenth the values found in the tables. For example,to find the number of cable yards when Width-W-16.2 and Height-H-5.8,opposite 16 in "Width"column said under 6 in the"Height" column reg¢1.18. To correct for additional 0.2 foot of width,opposite 9 in the"Width" column and under 5 in the" t' column road 0.18 and cornet to.018. To correct for additional 0.8 foot in height, under 8 in "Haight" column aad opposite 16 in "Width"column read 0.88 and correct to.089. Therefore,the total cubic yards in the rven TRIANGLE for a depth of 1 foot-1.48+.018+.099-1.587 or approximately 50 cu.yds.per 100 feet. If width exceeds 40 feet,use one half real width and multiply result by 2. If both 0� width and height are larger than values given on table use one half of each value and multiply result by 4. j 16 c � � J i . go . 4,
