Answer: [tex]792\ m^2[/tex]
Step-by-step explanation:
Given
The length of the rectangular prism is [tex]l=12\ m[/tex]
width of the rectangular prism is [tex]w=8\ m[/tex]
height of the rectangular prism is [tex]h=15\ m[/tex]
The surface area of the rectangular prism is [tex]2[wl+lh+hw][/tex]
Put the values
[tex]\Rightarrow 2[8\times 12+15\times 12+15\times 8]\\\Rightarrow 2[96+180+120]=2\times 396\\\Rightarrow 792\ m^2[/tex]
The surface area of the rectangular prism is [tex]792\ m^2[/tex]
