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
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.
To find the density of the rectangular prism, we can use the formula:
Density = Mass / Volume
First, let's calculate the volume of the rectangular prism. The volume of a rectangular prism is given by the formula:
Volume = Length x Width x Height
Substituting the given values:
Volume = 3 cm x 2 cm x 1 cm = 6 cm³
Now, we can calculate the density using the formula:
Density = Mass / Volume
Density = 120 g / 6 cm³
Simplifying the division:
Density = 20 g/cm³
Therefore, the density of the rectangular prism is 20 g/cm³.
The correct answer is:
b) 20 g/cm3
To find the density of a rectangular prism, you need to divide its mass by its volume.
The given mass of the rectangular prism is 120 g.
To find the volume, multiply the length, width, and height of the prism:
Volume = Length x Width x Height
Volume = 3 cm x 2 cm x 1 cm
Volume = 6 cm3
Now, we can calculate the density by dividing the mass by the volume:
Density = Mass / Volume
Density = 120 g / 6 cm3
Density = 20 g/cm3
Therefore, the density of the rectangular prism is 20 g/cm3 (option b).
