Corrections for tenths of feet in width and nht may be made by co-dderin the numbers on the table from 1 to 9 as tenths ana taking one tenth the values ound 1 in the tables. For example,to find the number of cubic yards when Width-W-16.2 and Height-H-5.8,opposite 18 in"Width"column and under 5 in the"N ht" column read 1.18. To correct for additional 0.2 foot of width,oppoette 2 i- Wi th" column and under 5 in the"Height"oolu--read 0.18 and ooreeot to.018.:To correct s for additional 0.3 foot in height, under 8 in "Height" column and opposite 16 in dth"Dolt,--read 0.89 agnndu correct to.Ogg. Therefore,the total cubic yards in the riven TRIANGLE fora depth of 1 foot-1.4S+.Ol$i-.089-1.587 or approumstely 0 So. yds.per 100 Leet. 0 If width exceeds 40 feet,use one half real width and multiply result by 2. If both width and height aro larger than values given on table use one halt of each value and multiply result by 4. 16 • ! , f a �f
