Answer:
[tex]D.\ 4\frac{1}{2}[/tex]
Step-by-step explanation:
Remember : 1 1/2 = (2+1)/2 = 3/2
Formula :
[tex]\large \text Volume\ V \ of \ a \ rectangular \ prism \ =base\ \times\ height[/tex]
Then
[tex]V=\left( 2\times 1\frac{1}{2} \right) \times 1\frac{1}{2}[/tex]
[tex]=\left( 2\times \frac{3}{2} \right) \times \frac{3}{2}[/tex]
[tex]=3 \times \frac{3}{2}[/tex]
[tex]=\frac{9}{2}[/tex]
[tex]=\frac{8+1}{2} = \frac{8}{2} +\frac{1}{2} =4+\frac{1}{2} =4\frac{1}{2}[/tex]
