Question

a block has a mass of 23 grams and a volume of 10 cm³. using the table right, what material is the block made of?
material | density
--- | ---
wood | 0.9 g/cm³
glass | 2.3 g/cm³
aluminum | 2.7 g/cm³
iron | 7.8 g/cm³

○ wood
○ glass
○ aluminum
○ iron

Explanation:

Step1: Recall density formula

$
ho = \frac{m}{V}$

Step2: Substitute given values

$
ho = \frac{23\ \text{g}}{10\ \text{cm}^3} = 2.3\ \text{g/cm}^3$

Step3: Match density to table

Compare calculated density with table values.

Answer:

Glass
