A first step is converting the 1 8 inch to a metric quantity. You have obtained 0.0031 m. It follows that your one square meter sheet is in reality a box of volume. V = 1 m 2 × 0.0031 m = 0.0031 m 3 . Since this "box" weighs 5.5 kg the volumetric density ρ of the material is given by. ρ = 5.5 k g 0.031 m 3 = 1774.2 kg/m 3. harvard cs50 web programming
