Question 227303: two suitcases are similar rectangular solids. The length of the second suitcase is twice the length of the first. The first suitcase has a volume of 1568 cubic inches what is the volume of the second suitcase in cubic inches.
Is there a formula for this. My son and I have tried and tried and just can't do this. Thank you

Two suitcases are similar rectangular solids.
The length of the second suitcase is twice the length of the first.
The first suitcase has a volume of 1568 cubic inches.
What is the volume of the second suitcase in cubic inches?
:
Since the suitcases are similar, we can assume the width and height of the second suitcase, is also twice the first;
:
First suitcase
L * W * H= 1568
:
2nd suitcase
2L * 2W * 2H = 8*L*W*H
:
Replace L*W*H with 1568
8(1568) = 12544 cu/in
