There are 2 faces 7 x 5

[tex]2*(5*7)=2*35=70ft^2[/tex]

There 2 faces 5 x 5

[tex]2*(5*5)=2*25=50ft^2[/tex]

there are 3 faces 5 x 12

[tex]4*(5*12)=4*60=240ft^2[/tex]

There are 2 faces 7 x 7

[tex]2*(7*7)=2*49=98ft^2[/tex]

Now only we have to sum all of them together

[tex]98+240+50+70=458ft^2[/tex]
