You can put this solution on YOUR website!
this is a perimeter problem minus 1 top side, total(t) square inches
the top and bottom are l*w
the two long sides are h*l
the two short sides are h*w
t=%28lw%29%2B2%28hl%29%2B2%28hw%29
since theres only the bottom we dont multiply by 2 for the lw sides
t=%286%2A10%29%2B2%285%2A6%29%2B2%285%2A10%29
t=%2860%29%2B2%2830%29%2B2%2850%29
t=%2860%29%2B60%2B100
t=220
