Answer:

268 squared inches

Explanation:

The minimum amount of wrapping paper to cover the box completely can be calculated by determining the total surface area of the rectangular prism.

For a rectangle, area = length × width

The opposite surfaces are equal in the prism, thus;

Area of first surface = length × width

= 8 × 10

= 80 square inches

Area of the second surface = length × width

= 10 × 3

= 30 square inches

Area of the third surface = length × width

= 8 × 3

= 24 square inches

Total surface area = 2 × Area of first surface + 2 ×Area of the second surface+ 2 × Area of the third surface

= 2 ×80 + 2 × 30 + 2 × 24

= 160 + 60 + 48

= 268

Therefore the minimum amount of wrapping paper required is 268 square inches.
