The chest, on that day of moving, had been set in the new attic, which was smaller than the other, and less frightening, perhaps because gaps in the cedar-shingled roof let dabs of daylight in. When the roof was being repaired, the whole space was thrown open to the weather. This is the answer.
409,200,000,000
rule 1: place point where there is one non-zero number to the left of the decimal point
so that would be after 4
now simply count the number of spaces the decimal point have "moved" from the original number
this will be the exponent of 10
so
409,200,000,000
the point in the original equation was supposed to be at the very end of the number
like this
409,200,000,000.000
we put the decimal point after 4
and now we count
that will be 11 spaces
so our answer is
4.092 * 10^11
