Note: Vol. = volume. Since the bolt has an irregular shape, find its volume by displacement only. 1. Calculate the volumes of the samples used in Procedure step 2. Record the calculated
volumes in Table 2.2. Why could we not find the volume of the bolt by this method?
2. How did you find the volume of the PE rod using the displacement method?
Note: 1 cm = 1 mL.
Because PE floats, push the rod under the water with a very small object, such as a
pin, and volume of the pin is negligible and can be ignored.
