Solution
The correct option is
A
392 sq in
The given box is in the shape of a cuboid.
Three sides are named as A, B and C
The corresponding sides opposite to A, B and C are equal.
Surface area of side A = length
×
width
Length of side A = 12 in
Width of side A = 5 in
Surface area of A = 12
×
5 = 60 sq in
Surface area of side B = length
×
width
Length of side B = 12 in
Width of side B = 8 in
Surface area of B = 12
×
8 = 96 sq in
Surface area of side C = length
×
width
Length of side C = 8 in
Width of side C = 5 in
Surface area of C = 8
×
5 = 40 sq in
Total surface area = 2
×
( +
surface area of A+ surface area of side B + surface area of side C)
= 2(60 +96+ 40) = 2(196) = 392
Hence, the surface area of the shoe box is 392 sq in.
