Answer 2

To get the amount of paper required to cover the box, we find the area of the box. 
The dimensions of the box are as follows:
length=21/2 ft
width=11/2 ft
height=4 ft

Area of the box is given by the formula:
SA=2lw+2lh+2hw
SA=2(21/2×11/2)+2(21/2×4)+2(11/2×4)
SA=2(231/4)+2(42)+2(11/2×4)
SA=115.5+84+44
SA=243.5  ft²
Stella will need 243.5 ft²
