we know that

4 1/2----> (4*2+1)/2-----> 9/2

[surface area of the box]=2*[area of the base]+[perimeter of the base*height]
[area of the base]=15*7------> 105 in²
perimeter of the base=2*(15+7)-----> 44 in

[surface area of the box]=2*[105]+[44*9/2]---->   210+198---> 408 in²

the answer is
408 in²
