Write a MATLAB function that will determine the weight of a rod on Jupiter's moon Callisto in units of pounds$-$force given the rod volume in cubic meters. The specific gravity of the rod is $4\mathrm{.}7.$ Gravitational acceleration on Callisto is $1\mathrm{.}25$ meters per second squared. For example, if a rod on the surface of Jupiter's moon Callisto has a volume of $0\mathrm{.}3$ cubic meters, you might test your function with $0\mathrm{.}3$ cubic meters in the volume variable.

Name your function CallistoWeight
