Look at this prism and its net.
what is the surface area of this rectangular prism?

We know that

its net
[the surface area of this rectangular prism]=4*11+3*11+3*4*2+4*11+3*11
[the surface area of this rectangular prism]=178 ft²

the prism
[the surface area of this rectangular prism]=2*[area of the base]+[perimeter*height]
[the surface area of this rectangular prism]=2*[4*3]+[2*(4+3)*11]
[the surface area of this rectangular prism]=24+[14*11]> 178 ft²

the answer is
178 ft²
