When Jorge put the pots and pans in the sink,the water level in the sink rose 0.6 inches. If the sink is a rectangular prism wit

Viktor [21]

$V_1$ - volume without pots and pans
$V_2$ - volume with pots and pans
$V_2-V_1$ - volume of pots and pans

$V_1=17\cdot23\cdot h=391h\ in^3\\ V_2=391(h+0.6)=391h+234.6\ in^3\\
V_2-V_1=391h+234.6-391h\\
V_2-V_1=234.6 \ in ^3$
