Brown paper required = 2(lb+bh+hl)
= 2(2×1+1×4+4×2)
= 2(2+4+8)
= 2(14)
= 28sq. feet
= 2(2×1+1×4+4×2)
= 2(2+4+8)
= 2(14)
= 28sq. feet

Answer:
28 ft² of brown paper will Evan need to wrap the entire box .
Step-by-step explanation:
Formula
Total surface area of a cuboid = 2 (lb + bh + hl)
Where l is the length , b is the breadth and h is the height .
As given
Evan is wrapping a shipping box in brown paper.
The box is in the shape of a right rectangular prism. The box has a length of 2 ft, a width of 1 ft, and a height of 4 ft.
Put all the values in the formula
Total surface area of a cuboid = 2 × ( 2 × 1 + 1 × 4 + 4 × 2)
= 2 × (2 + 4 + 8)
= 2 × 14
= 28 ft²
Therefore 28 ft² of brown paper will Evan need to wrap the entire box .
