Jenny need 166 square inches of wrapping paper to wrap the present.
Solution:
Length of the box = 4 in
Breadth of the box = 5 in
Height of the box = 7 in
Surface area of the box = 2(lb + bh + lh)
= 2( 4 × 5 + 5 × 7 + 4 × 7)
= 2(20 + 35 + 28)
= 2(83)
Surface area of the box = 166 in²
Hence Jenny need 166 square inches of wrapping paper to wrap the present.
