Describe one way that the student can determine the exact volume of one of the three blocks

Density is defined as an object's mass per a given unit of volume. So, if you know the object's density, and you're able to weigh it, you can determine its volume with the equation:

Volume = weight / density

There is a link in the Resources section to a web page which lists the densities of some common materials. Note that density changes with pressure or temperature.

the small 0.38-kg slider is known to move from position a to position b along the vertical-plane slot. determine (a) the work done on the body by its weight and (b) the work done on the body by the spring. the distance r = 0.70 m, the spring modulus k = 154 n/m, and the unstretched length of the spring is 0.53 m
