Solution:
Surface area of the prism = 2(lw+lh+hw)
Where
l=length
w=width
h=height
In the question,
l=5m
w=3m
h=11m
[tex]\begin{gathered} Surface\text{ area = 2\lparen\lparen5\rparen\lparen3\rparen+\lparen5\rparen\lparen11\rparen+\lparen11\rparen\lparen3\rparen\rparen} \\ =\text{ 2\lparen15+55+33\rparen} \\ =2(103) \\ =206m^2 \end{gathered}[/tex]
The answer is 206 cubic meter
