A block of metal is 6.88 cm long, 2.03 cm wide, and 1.85 cm high. It has a mass of 215.1 grams. What is the density of this metal.

I've tried adding all the cm up and squaring them, dividing them, multiplying but i can't get the answer

You're guessing.

Volume = l x w x h
density = mass/volume.

volume = 6.88 x 2.03 x 1.85 = ? cubic centimeters

density = g mass/volume cc = ?
