Question

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?

Answer 1

12.58 g/cm³

Step-by-step explanation:

V = 7×4×1 = 28cm³

ρ = m/V = 352/28 ≈ 12.58 g/cm³

Answer 2

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
