5
centimeters on a side and weighs
32
grams. Complete parts (a) and (b) below.
a. What is the density of the cube of wood?
b. Will it float in water?
a. The density of the cube of wood is
nothing
g divided by cm cubedg/cm3.
(Round to two decimal places as needed.)
b. Will the cube of wood float in water?
A.
The cube will sink since its density is less than 1
g divided by cm cubedg/cm3.

g divided by cm cubedg/cm3.
Explanation / Answer
(a) Given side of cube = 5cm => volume of cube = 5*5*5 = 125cm3.
Given, mass of the wood = 32grams
=> density of cube of wood = mass/volume = 32/125= 0.256 g/cm3.
(b) The wood cube will float. The density of water is 1 g/cm3 and density of wood cube is 0.256 g/cm3 . Since the density of wood is less than the density of water, it will float in water.
