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:

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=\frac{m}{V}

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