Calculate the density of a rectangular metal bar that is 7.00 cm long, 4.00 cm wide, and 1.00 cm thick, with a mass of 352 g.

Question

GracieHelena · Answer

Density is mass divided by volume (d=m/v) To calculate volume you multiply the length, width, and height of the object (v=lwh) In this example, we get a product of 28 So 352/28 is 12.57142.... Round to the nearest decimal place indicated in your instructions or keep as is
