Step-by-step explanation:

Answer 2

Answer:

$D.\ 4\frac{1}{2}$

Step-by-step explanation:

Remember : 1 1/2 = (2+1)/2 = 3/2

Formula :

$\large \text Volume\ V \ of \ a \ rectangular \ prism \ =base\ \times\ height$

Then

$V=\left( 2\times 1\frac{1}{2} \right) \times 1\frac{1}{2}$

   $=\left( 2\times \frac{3}{2} \right) \times \frac{3}{2}$

   $=3 \times \frac{3}{2}$

   $=\frac{9}{2}$

   $=\frac{8+1}{2} = \frac{8}{2} +\frac{1}{2} =4+\frac{1}{2} =4\frac{1}{2}$
