Calculating Load Weights Using Volume (Use Table 1.2 in M035)
Example 1
Calculate the weight of the spruce lumber.
Step 1: Complete the calculation
Volume of a rectangle
Volume = L x W x H
= 12 ft x 4 ft. x 3 ft
= 144 ft³
Step 2: Use Table 1.2 (Volume) to find Spruce Lumber
Spruce Lumber = 28 lbs/ft³
Step 3: Calculate the Weight
=144 x 28 lb.
= 4,032 lbs
