The volume of a cube is an edge length cubed, so an edge length would be the volume to the 1/3 power. Therefore, the edge length of this 1200 cm³ cube can be written as 
cm. This also equals 2∛150 cm and is approximately 10.627 cm.
Answer:
It will take Ellie 64 minutes to put as many boxes as possible.
Step-by-step explanation:
Let us work with meters.
The dimensions of Ellie's boxes in meters are: 0.45m by 0.40m by 0.35 ( <em>to convert from centimeters to meters we just divide by 100, because 1m =100cm).</em> therefore the volume of each box is:
<em></em>
Now the dimensions of the empty van are 3.6m by 1.6m by 2.1 m, therefore its volume is:
So the amount of boxes that Ellie can put in the van is equal to the volume of the van divided by the volume
of each box:
So 192 boxes can be put into the van.
Now Ellie can put 3 boxes in the van in 1 minute, therefore the amount of time it will take her to put 192 boxes into the van will be:
So it takes Ellie 64 minutes to put as many boxes into the van as she can.
