## Homework Statement

A piece of aluminum is completely covered with a gold shell to form an

object of weight W. When you suspend the object from a spring balance

and submerge it in water, the balance reads T. The density of water,

aluminum and gold is ρw, ρa, and ρg, respectively. The gravitational

acceleration is g.

What is the weight of the gold covering the object? Express

your answer in the given constants.
