<u>What we'll do:</u>
A method to find whether an object will float or sink in a liquid is to find it's specific gravity with respect to the liquid, The Specific Gravity tells us the percentage of object's mass which will be submerged in water
<u>Finding the Specific Gravity:</u>
<u>Density of Box:</u>
Density = Mass / Volume
Density = 80 grams / 78 cm³
Density = 1.02 grams/cm³
<u>Specific Gravity of Box with respect to water:</u>
Specific Gravity = Density of Box / Density of Water
we know that density of water is 1 gm/cm³, plugging the values
Specific Gravity = 1.02 / 1
Specific Gravity = 1.02
Hence, 102% of the object will be under water
Q. but I've only heard about 100% of something, how can something be more than 100%?
A. The answer is that the extra 2% over the 100% is providing to the object being even deeper underwater
