Do this problem on a separate piece of engineering paper using the standard engineering problem format and specifications. Express the answers to three significant figures.

Water has a density $($mass$/$unit volume$)$ of $1\mathrm{.}94$ slug$/$ff ${?}^3.$ That is to say that one cubic foot of water has a mass of $1\mathrm{.}94$ slugs.

a$.$ What is the density expressed in SI units?

The unit weight of a material is defined as the force due to gravity $($weight$)$ of the material per unit volume $($W$/$V$).$

b$.$ What is the unit weight of water in FPS units?

c$.$ What is the unit weight of water in SI units?
