Complete question
The diagram show a block of modelling clay 12cm 6cm and 2cm.
The density of the modelling clay is 1.25g/cm3. What is the mass of the block of clay?
Answer:
The mass of the block is 180g
Step-by-step explanation:
Given
Density = 1.25 g/cm³
Required
Mass of the block
Eben though the diagram of the block is missing, the question can still be solved.
First, the volume needs to be calculated.
Volume = lengy * breadth * height
Volume = 12 *,6 * 2
Volume = 144cm³
Now we have Volume and density.
The relationship between these two is as follows;
Density = mass/volume
Substitute for density and volume.
1.25 = mass/144
Multiply 144 to both sides
144 * 1.25 = mass/144 * 144
180 = Mass
Mass = 180
Hence, the mass of the block is 180g
