Question

A block of oak has volume of 200 cubic centimeter and weighs 0.12 kilograms. What is its density? Will it floats on water?

Answer 1

Answer:

Density  = Mass (grams) / Volume (Milliliters)

Density = 120 grams / 200 ml

Density = .60 grams per ml

Density is less than 1 so it will float on water.

Answer 2

Step-by-step explanation:

It is given that,

Volume of the block of oak, V = 200 cc

Mass of the block of oak, m = 0.12 kg = 120 grams

The density of any substance is given by mass per unit volume. mathematically, it is given by :

$d=\dfrac{m}{V}$

$d=\dfrac{120\ g}{200\ cm^3}$

$d=0.6\ g/cm^3$

So, the density of the block of oak is $0.6\ g/cm^3$. The density of water is $1\ g/cm^3$. So, it will float on water as the density of the block of oak is less than water.
