Mass of silver to cover a 2.0 x10^2 cm2 object with .20mm thick layer

[geoti8]

Homework Statement

if an object to be coated in a .20mm thick layer with a surface area of 2.0x10^2 cm^2, what is the mass of the silver required? (density of silver is 10.49 g/cm^3)

Homework Equations

d=m/v , surface area formula? not sure which one

The Attempt at a Solution

i know i am to use the surface area and depth info to calculate the volume of silver required to plate the object, then use the density provided to convert it to grams..

but not sure where to start..
