Answer:
[tex]\Huge \boxed{\mathrm{2 \ cm }}[/tex]
Step-by-step explanation:
[tex]\sf Volume \ of \ cuboid= length \cdot width \cdot height[/tex]
The width is 8.5 cm.
The height is 13 cm.
The volume is 221 cm³.
[tex]221 = l \cdot 8.5 \cdot 13[/tex]
Solving for [tex]l[/tex]
[tex]221=l \cdot 110.5[/tex]
Dividing both sides by 110.5
[tex]2=l[/tex]
The length is 2 cm.
