Answer 1

Surface area of the prism = 2(lw+lh+hw)

Where

w=width

h=height

In the question,

l=5m

w=3m

h=11m

`\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}`

The answer is 206 cubic meter
