Polycarbonate plastic has a density of 12 g/cm3. A photo frame is contructed feom two 3 I n sheets of polycarbonate. Each sheet measures 28 cm by 22 cm. What is the mass of the photo frame

What 3 l n sheets? Is that the thickness.If that is 3" (inch) thickness, convert to cm (2.54 cm to the inch).
volume = length x width x thickness
Then mass = volume x density. Substitute and solve for mass.
