Answer:
Stella will need 39.5 square feet of paper for wrapping the box.
Solution:
Given that length of box = [tex]2 \frac{1}{2} \text { feet }[/tex], width of box = [tex]1 \frac{1}{2}[/tex] feet and height of box = 4 feet
Area of paper required for wrapping the box = surface area of rectangular prism box
Surface area of rectangular prism box is given as
[tex]=2(\text { width } \times \text {length }+\text {length} \times \text {height}+\text {height} \times \text {width})[/tex]
[tex]=2(1.5 \times 2.5+2.5 \times 4+4 \times 1.5)[/tex]
[tex]= 2( 3.75 + 10 + 6) = 2 \times 19.75 = 39.5 square feet.[/tex]
Hence Stella will need 39.5 square feet of paper for wrapping the box.
