Question

Which tools would be necessary to determine whether or not a large regular block will float, without using water?

Answer 1

Scale and measuring tape.
To determine the mass and volume, you can find the density. The block will float if its density is less than that of water.

Answer 2

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:

`V=wide*lenght*height`

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

`\rho=(m)/(V)`

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