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
