I dont even know where to begin to solve this problem please help

A 6.5 g piece of copper was rolled out into a thin sheet measuring 24.0 cm x 18.0 cm. The density of copper is 8.90g/cm3

1. Calculate the volume of the sheet of metal

2. Calculate the thickness of the sheet of copper

V = Volume = length*width * thickness =L w t

V = 24 * 18 * t

6.5 mass = V*density = 24 * 18 * t * 8.9

so

t = 6.5 /(24*18*8.9)

then

V = 24 * 18 * t

i think i understand is the volume 57.85

well volume = mass/density = 6.5/8.9

=.73 cm^3

I got .0017 for t
