Wow !  Questions like these just seem like busy-work.

 

Box surface area= 4(16x11)+ 2(11x11)  in2      we will need to subtract the area of the bottom of the cylinder  BUT we need to add the top surface of the cylinder when we calculate the surface area of the cylinder .....so just compute the surface area of the box and add the lateral area of the cylinder

    cylinder lateral area =  pi x d x h =  pi x 8 x 9 in2

 

Add the reds to get total in2
