Will a plastic block that has sides that measure 9 cm and its mass is 19.2 grams float on water?

• science -

Eric, this really depends on if the block is porus. Could you please respond back with more details? I am willing to help. Also, what is the surface tension of the water?

• science -

Find the Density, which is equal to mass/volume, and use the equation density of the block/ density of water. If the density of the block is lower than water, then it will float, if not then it will sink or be submerged. To calculate the density of the block take the weight and divide by (3cm *3cm*3cm).
