The mass of a block made of certain material is 13.5 kg and its volume is `15 xx 10^(-3) m^3`.
Will the block float or sink in water when released? Give a reason for your answer.

Explanation

To determine whether the block will float or sink in water, we need to compare the weight of the block with the buoyant force acting on it when it is submerged in water.

### Step-by-step Solution:

1. **Calculate the Weight of the Block:**
The weight \( W \) of the block can be calculated using the formula:
\[
W = m \cdot g
