Explanation
The volume of a rectangular prism is given by:
[tex]\text{Volume}=\text{ length}\cdot width\cdot height[/tex]then,Let
length= 3/4
width=1/2
heigth=2/3
Now, replace,
[tex]\begin{gathered} \text{Volume}=\text{ length}\cdot width\cdot height \\ \text{Volume}=(\frac{3}{4}\cdot\frac{1}{2}\cdot\frac{2}{3}) \\ \text{Volume}=\frac{3\cdot1\cdot2}{4\cdot2\cdot3}=\frac{1}{4} \\ \text{Volume}=\frac{1}{4}\text{cubic units} \end{gathered}[/tex]I hope this helps you
