$2.$
$a)$$0,000069$ $km^{3}$ $=$ $0,69$ $hm^{3} =$ $69$ $dam^{3} =$ $69000$ $m^{3}$

$b)$$8265$ $m^{3} =$ $8265000$ $dm^{3} =$ $8265000000000$ $mm^{3} =$ $8265$ $dam^{3}$

$c)$$1785000$ $m^{3} =$ $1785$ $hm^{3} =$= $0.001785$ $km^{3}$

$d)$$0,25$ $m^{3} =$ $250000$ $cm^{3} =$ $250$ $dm^{3} =$ $250000000$ $mm^{3}$


$3.$
$a)$$812000$ $m^{3} +$ $575000$ $m^{3} +$ $0.812$ $m^{3} = 1387000,812$ $m^{3}$
$b)$$5000$ $dam^{3} + 125000$ $dam^{3} + 173,65$ $dam^{3} =$ $130173,65$ $dam^{3}$
$c)$$0,000003$ $m^{3} +$ $18$ $m^{3}$ $?$ $142000$ $m^{3}$
