Answer:
592 Square inches
Explanation:
We solve the above question by calculating the surface area of the rectangular box
A =2(wl + hl + hw)
w = Width = 8 inches
l = Length = 12 inches
h = Height = 10 inches
The square inches of wood would Mitchel need to build the box is calculated as:
Surface Area = 2 × (8 × 12 + 10 × 12 + 10 × 8) = 592 Square inches
