8,000:20,000
Let's write another ratio
x:40,000
We can write a percent proportion.
![\frac{8,000}{20,000} =\frac{x}{40,000}](https://tex.z-dn.net/?f=%5Cfrac%7B8%2C000%7D%7B20%2C000%7D%20%3D%5Cfrac%7Bx%7D%7B40%2C000%7D)
We can see that the relationship between the denominators is multiplied by 2 so that means the relationship between 8,000 and x is x is 2 times greater than 8,000

the volume of the box increases 48 times compared to the 1st one.
Step-by-step explanation:
Volume of the box (1) = LWH
- length of a box is increased 4 time = 4L
- width is increased 4 times = 4W
- the height is tripled = 3H
=> The new volume of the box = 4L * 4W * 3H = 48LWH
So the volume of the box increases 48 times compared to the 1st one.
