Answer 1

`D.\ 4(1)/(2)`

Explanation:

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

Formula :

`\large \text Volume\ V \ of \ a \ rectangular \ prism \ =base\ *\ height`

Then

`V=\left( 2* 1(1)/(2) \right) * 1(1)/(2)`

`=\left( 2* (3)/(2) \right) * (3)/(2)`

`=3 * (3)/(2)`

`=(9)/(2)`

`=(8+1)/(2) = (8)/(2) +(1)/(2) =4+(1)/(2) =4(1)/(2)`
