Question

A cube of 2.13 inches on the side has a mass of 36.6 g. What is the density in ( g)/(c)m3? 1 inch =2.54 cm

Answer 1

Side = 2.13 inch

1 inch = 2.54 cm

Side = 2.13 inch = 2.13×2.54 = 5.4102 cm

mass = 36.6g

Volume = side³ = (5.4102)³ = 158.36 cm³

Density = $\frac{mass}{volume}$ = $\frac{36.6g}{158.36cm^3}$

Density = 0.2311 g/cm³
