The width and height of a 2 x 4 is piece of lumber are actua
The width and height of a 2 x 4 is piece of lumber are actually 1.5 x 3.5 in. Assume that the uncertainty in these quantities is negligible. The length of a 2 x 4 is measured to be 72
Solution
378 +/- 0.525
| Average | Min | Max | |
| W | 1.5 | 1.5 | 1.5 |
| H | 3.5 | 3.5 | 3.5 |
| Length | 72 | 71.9 | 72.1 |
| Volume | 378 | 377.475 | 378.525 |
