6

Step-by-step explanation:

Let's call the number of red cubes that Sam has r, and the number of yellow cubes that she has y.

Since the sum of the number of cubes is 20:

r+y=20

Since she has 8 more yellow cubes than red ones:

y=r+8

You can now plug this back into the first equation:

r+(r+8)=20

2r+8=20

2r=12

r=6

Therefore, Sam has 6 red cubes. Hope this helps!
