Answer:
268 squared inches
Step-by-step 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.
