The firewood weighs $1,558$ pounds.
RECALL: $P=BR$ where $P$=part or amount (percentage), $B$=base, and $R$=rate The given problem has: $B= 1640$ pounds $R= 95\%$ Use the formula above to find the weight of the firewood $=1640 \times 95\% \\=1640 \times 0.95 \\=1558$ Thus, the firewood weighs $1,558$ pounds.
