Term
| What tools are needed to measure the volue of an irregular shaped item? |
|
Definition
| You would need a large container full of water and a measuring cup to measure the volume of the water displaced by the statue when it is placed water. In order to measure the mass you would need a balance and standardized weights to measure the mass of the statue. In order to find its denisty, you could use a calculator to divide the mass by its volume. |
