Latest version.
- (a) Average height determination of wood within the box: Open the box and measure the internal height of the box (h). Take three measurements (d) along each end of the stack by measuring from the bottom of a straight edge placed across the top of the box to the highest point on the two outermost top pieces of wood and the center-most top piece of wood rounding measurements down to the nearest 1/8 inch. However, if there are obviously pieces missing out of the top layer of wood, additional height measurements shall be taken at the highest point of the uppermost pieces of wood located at the midpoints between the three measurements on each end of the stack. (See Figure 6.) The average height of the stack is calculated by averaging these measurements and subtracting from the internal height of the box.Figure 6.Calculate the average height of stack.Average Height of Stack = h - [(d<<super>>1 + d<<super>>2 + d<<super>>3 + d<<super>>4 + d<<super>>5 + d<<super>>6) / 6](b) Average width of the wood within the box: Determine the width of the stack of wood at three places along the top of the stack. These measurements shall be taken on both ends and in the middle of the box, measuring the inside distance from one side of the box to the other, perpendicular to the long axis of the wood. (See Figure 7.)Figure 7.Calculate the average width.Average Width = (W<<super>>1 + W<<super>>2 + W<<super>>3) / 3(c) Average length of the pieces of wood: Remove the wood from the box and select the five pieces with the greatest girth. Measure the length of the five pieces, measuring from center-to-center, as shown in Figure 8.Figure 8.Calculate the average length of the five pieces.Average Length = (L<<super>>1 + L<<super>>2 + L<<super>>3 + L<<super>>4 + L<<super>>5) / 5(d) Calculate the volume of the wood within the box.Volume of WoodAverage HeightAverage WidthAverage Length(In cu ft)=(In inches)X(In inches)X(In inches)/1728 In<<super3/ft<<super>>3(e) For boxes of wood which are packed with the wood ranked in two discrete sections, which are perpendicular to each other, calculate the volume of wood in the box by determining the average height, width, and length as in (a), (b), and (c) above for each discrete section and totaling the calculated volumes of the two sections. Except that the width measurement for V 2 shall be taken from the inside edge of the box adjacent to V 2 to the plane separating V 1 and V 2. (See Figure 9.)Figure 9.TOTAL VOLUME = V1 + V2HISTORY1.
