Given:
Dimensions of a rectangular prism are 6 meters by 3 meters by 12 meters.
To find:
The surface area of the prism.
Solution:
The surface area of a rectangular prism is:
[tex]A=2(lb+bh+hl)[/tex]
Where, l is length, b is breadth and h is height.
Putting [tex]l=6,b=3,h=12[/tex], we get
[tex]A=2(6\times 3+3\times 12+12\times 6)[/tex]
[tex]A=2(18+36+72)[/tex]
[tex]A=2(126)[/tex]
[tex]A=252[/tex]
Therefore, the surface area of the prism is 252 square meters.
