Sally used 8 cubes to make this square frame that has 3 cubes on each side. If she uses 20 cubes to make a square frame, how many cubes will be on each side of the frame? Think of using objects to help you solve this problem.

5

Step-by-step explanation:

move it to the other side

step-by-step explanation:

the 8 in 8,420 is in the thousands place so it's value is 8 thousand.

the 8 in 6,870 is in the hundreds place so it's value is 8 hundred.

divide 8000 by 800 to find the answer:

8000 / 800 = 10

the 8 in 8,420 is 10 times greater than the 8 in 6,870
