Question

A block of wood 5cm x 4cm x 3cm. It has a mass of 13.4g. What is the density of the wood?

Answer 1

The volume of a cube is given by s^3. So the volume of this block is 3cm x 3cm x3 cm = 27 cm^3.

 

density = mass/volume =27 g / 27 cm^3 = 1 g/cm^3.

 

the answer is 1 g/cm^3. I hope this helps!
