Once again super confused

Well, you see the yellow colored "face" Think of it as area. So we got a smaller square next to it right...just ignore it and look at the yellow square. So, how do you find the area? Length times width right? So, since this cube has 4 inches all over it, what do you think you have to do if a square has equal sides/measurements. You multiply 4*4, which is 16! NOTE: It is NOT asking for volume! Hope this helps!

vekshin1

The combination shows that the different groups of three that can be chosen for a newspaper photo is 10.

<h3>How to calculate the value?</h3>

From the information, Joyce, Karen and Paula are starters on their school basketball team.

The information is to illustrate the different groups of three that can be chosen for a newspaper photo.

This will be:

= 5!/3!(5 - 3)!

= 5!/3!2!

= (5 × 4 × 3 × 2 × 1)/(3 × 2 × 2)

= 20/2

= 10

There will be 10 groups.
