A cord of cut wood

Classical Mechanics Level 2

A cord is a volume of cut wood equal to a stack $8 \text{ ft}$ long, $4 \text{ ft}$ wide, and $4 \text{ ft}$ high. Approximately how many cords are in $1.0 \text{ m}^{3}?$

You should convert m into ft first: $1 \text{ m} \approx 3.3 \text{ ft.}$

0.3 cord 0.6 cord 6.0 cord 3.0 cord

$1 \: m^{3} = (3.3 ft)^{3} = 35.937 ft^{3}$

$1 \: cord = 8 ft \times 4 ft \times 4 ft = 128 ft^{3}$

$N \! o. \; o \! f \; cords \; in \; 1\: m^{3} = \frac { 1 m^{3} } {1 \: cord } = \frac { 1 m^{3} } {128 ft^{3} } = \frac { 35.937 ft^{3} } {128 ft^{3} } = 0.28075 \approx 0.3$

I used the same method. But accidentally I've selected 3.0 in spite of selecting 0.3
