1) OPTION D.
2) OPTION D.
Step-by-step explanation:
1) You can calculate the surface area of the rectangular prism with the following formula:
![SA=2(wh+lw+lh)](/tpl/images/0441/1894/3c8ea.png)
Where w is the width, h is height and l is the length.
The figure show you that:
![l=4m\\w=3m\\h=0.5](/tpl/images/0441/1894/1338f.png)
Then, the surface area is:
![SA=2[(3m*0.5m)+(4m*3m)+(4m*0.5m)]=31m^{2})](/tpl/images/0441/1894/3bb09.png)
2) You can calculate volume of the rectangular prism with the following formula:
![V=lwh](/tpl/images/0441/1894/edea1.png)
Where w is the width, h is height and l is the length.
When you substitute values, you obtain the following result:
![V=4m*3m*0.5m=6m^{3}](/tpl/images/0441/1894/0bc34.png)
