    @ghazi is right the surface area which is 2 (lh) + 2(lw) + 2(wh) Length= 10 Width= 8 and Height= 5 so you do 2 times 10 times 8 plus 2 times 10 times 5 plus 2 times 8 times 5

    then you should be able to multiply those and get your answer

    So... 2 times 10 is 20 times 8 is 160 plus 2 times 10 is 20 times 5 is 100 plus 2 times 8 is 16 times 5 is 80

    \[boxes=\frac{ 20,000 }{[ 2(10*8)+2(10*5)+2(8*5) ]}=\frac{ 20,000 }{ 340 }=58.82\]
