The surface area of the cereal box is 290 in².
Surface area of box
The surface area of the cereal box measuring 3 in 8 in 11 in is calculated as follows;
S.A = 2(Lh + Lw + hw)
where;
- L is the length = 3 in
- h is the height = 8 in
- W is the width = 11 in
Substitute the given parameters and solve for the surface area
S.A = 2(3 x 8 + 3 x 11 + 8 x 11)
S.A = 2(24 + 33 + 88)
S.A = 290 in²
Thus, the surface area of the cereal box is 290 in².
