Density is calculated by dividing the mass of an object by its volume. The formula for density is:
Density = Mass / Volume
To find the density of the rectangular prism, we need to find the volume first. The volume of a rectangular prism is calculated by multiplying its length, width, and height. The formula for volume is:
Volume = Length × Width × Height
Using the given values:
Volume = 3 cm × 2 cm × 1 cm = 6 cm³
Now we can calculate the density:
Density = Mass / Volume = 120 g / 6 cm³ = 20 g/cm³
Therefore, the density of the rectangular prism is 20 g/cm³.
The correct answer is (b) 20 g/cm³.
The properties of a rectangular prism are listed below:
Mass = 120 g
Length = 3 cm
Width = 2 cm
Height = 1 cm
What is the density of the rectangular prism?
a) 10 g/cm3
b) 20 g/cm3
c) 360 g/cm3
d) 720 g/cm3
