if 1.00-in cube of copper measures 2.54 cm on a side(copper=8.96 g/cubic cm)
(copper=8.96 g/cubic cm) 2.54cm * 2.54cm * 2.54cm = 16.387 cubic cm 8.96 * 16.387 = 146.8275 g. The mass of 1.00-in (2.54cm) cube of copper is 146.8275 g
Answer is 22.74 gm you can just multiply 8.96 x 2.54..
volume of copper: 2.54 cm x 2.54 cm x 2.54 cm = 16.39 cm^3 16.39 cm^3 x (8.96 g/ cm^3) = 146.8 grams
Volume of a cube = (side)^3 => (2.54)^3 => 16.387 Now, density = mass/volume => 8.96 = g / 16.387 => 8.96 * 16.387 = g => g = 146.827 grams.
