Help? Step by step pls?

The depth of the orange juice is 4 cm now.

Step-by-step explanation:

Volume of a Rectangular Prism or Cuboid

A rectangular prism (cuboid, or a box as we commonly call it) with a width W, length L, and height H has a volume of:

Note WL is the area of the base Ab=WL, thus:

Jane has a carton of orange juice of dimensions:

W=6 cm

L = 10 cm

H = 20 cm

It's actually filled with h=8 cm of orange juice, thus the volume of juice is:

When Jane turns the carton over the shaded face (the one with a base of 6 cm by 20 cm), the volume of juice is, of course, the same, but the new height can be calculated by finding the new area of the base:

The volume of the juice when turned over is:

Where H' is the required height. Solving for H':

The depth of the orange juice is 4 cm now.

the ratio of balloons to tables is 5: 2 and the constant variation is 5.

the equation is y=5x
