Q. One cubic centimeter iron weight $12.5 gm$ . Then solid piece of iron whose dimensions are $35 cm \times 25 cm \times 20 cm$ will weigh

$220 kg$

$218.75 kg$

$318 kg$

None of these

$Vol = l \times b \times h$
$= 35 \times 25 \times 20$
$= 17500 cm^{3}$
$1 cm^{3} = 12.5 gm$
$∴ 17500 \times 12.5 = 218.75 kg$
