ANSWER

[tex]T.S.A=1960m^2[/tex]

EXPLANATION

The diagram represents the net of a rectangular prism.

The dimensions are,

[tex]l=42m[/tex]

[tex]w = 14m[/tex]

and

[tex]h = 7m[/tex]

The total surface area of a rectangular prism is given by:

[tex]T.S.A=2(lw + lh + wh)[/tex]

We substitute the values to obtain,

[tex]T.S.A=2(42 \times 14 + 42 \times 7 + 14 \times 7)[/tex]

[tex]T.S.A=2(980)m^2[/tex]


[tex]T.S.A=1960m^2[/tex]
