Solution
Step 1
Draw the box
Step 2
Write an expression for the area of the box
[tex]S\mathrm{}A\text{ = 2}lw\text{ + 2lh + 2}hw[/tex]
Where
l = 12ft = length
w = 10ft = width
h = 6ft = height
Step 3
Find the surface area of the cuboid
[tex]\begin{gathered} S\mathrm{}A\text{ = 2(12)(10) + 2(}12)(6)\text{ + 2 }(6)(10) \\ S\mathrm{}A\text{ = 240 + 144 + 120 =504}ft^2 \end{gathered}[/tex]
