In order to calculate the value of the expression 1.4 * 0.2 * 1.8, first let's calculate the product of the first two numbers.
To multiply 1.4 by 0.2, we can first multiply 1.4 by 2 and then divide the result by 10:
![\begin{gathered} 1.4\cdot2=2.8 \\ 2.8\colon10=0.28 \end{gathered}](https://img.qammunity.org/2023/formulas/mathematics/high-school/rtd1fmckmfuexjk1wiww12012oezcj7m0o.png)
Now we can calculate the product of 0.28 and 1.8.
To do so, we can multiply 0.28 by 18 and then divide the result by 10:
![\begin{gathered} 0.28\cdot18=5.04 \\ 5.04\colon10=0.504 \end{gathered}](https://img.qammunity.org/2023/formulas/mathematics/high-school/7k92djfgf9a67xvh8e50gddg59ybi06b6g.png)
So the final result of the expression is 0.504.
