Answer:
Step-by-step explanation:
To determine if the bock will float you need:
- A scale to calcualte the weight of the block
- A ruler or metric tape to measure the block and calculate its volume
The block has 3 dimmentions: lenght, wide and height, its volume is:

Once calculated it and measured the weight, you calculate the density:

If the density of the block is smaller than the density of water (arroung 1000 kg/m3) the block will float.
