Chapter 7, Problem 5MCQ

To determine

To Express: The volume of the solid

  

Answer to Problem 5MCQ

  $V=8x^9$ option ‘B’ is correct.

Explanation of Solution

Given information:

The figure

  

Concept and Formula Used:

Volume of cuboid $V=l\times b\times h$

Calculation:

The given figure is

  

Where $l=x^2,b=4x^4\&h=2x^3$

Putting the value of length, breadth and height

  $\begin{array}{l}V=l\times b\times h\\ V=x^2\times 4x^4\times 2x^3\\ \text{Using }{a}^m\times a^n=a^{m+n}\\ V=8x^{2+4+3}\\ V=8x^9\end{array}$

Conclusion:

  $V=8x^9$ option ‘B’ is correct.
