Layla wants to build a wooden box with the volume of 45cubic centimeter. She started with a width of 3cm and a height of 3cm . How long should Layla make the box?

Respuesta :

The volume of the box is length*width*height

So length*3cm*3cm=45cm³

Let [tex]l=[/tex] the length of the box

We have
[tex]l*3*3=45[/tex]
⇒[tex]9l=45[/tex]
⇒[tex]l=5[/tex]

So the length should be 5 cm.
The answer should be 5 cm
