Answer:
520 square inches
Explanation:
To do this we just have to find the surface area of the box
The formula would be
SA=2lw+2lh+2wh
so we can assign these dimensions to a value
l: 10
w: 14
h: 5
and plug our values in
SA=2(10)(14)+2(10)(5)+2(14)(5)
and simplify
SA=2(140)+2(50)+2(70)
SA=280+100+140
SA= 520
