1.2 mm

a) Calculate the <em>volume</em> of the block

<em>V </em>= 50 g x (1 cm^3/8.64 g) = 5.79 cm^3

b) Calculate the <em>height</em> of the block

The formula for the volume (V) of a block is

<em>V = lwh </em>

where

<em>l</em> = the length of the block

<em>w</em> = the width of the block

<em>h</em> = the height of the block

We can solve this formula for the height.

<em>h = V</em>/(<em>lw</em>)

∴ <em>h</em> = 5.79 cm^3/(10 cm x 5 cm) = 0.12 cm = 1.2 mm
