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

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
