Container A was filled with water to the brim. Then, some of the water was poured into an empty Container B until the height of the water in both containers was the same. Find the new height in both water containers

The new height of the water container is equal to 66.7 centimeters.
For Container A:
For Container B:
First of all, we would determine the volume of the water in Container A:
Mathematically, the volume of a rectangular prism is given by this formula:
[tex]V = L \times W \times H[/tex]
Where:
Substituting the given parameters into the formula, we have;
[tex]V = 25 \times 30 \times 40[/tex]
V = 30,000 cubic centimeters.
Note: The volume of the two containers must be the same.
The new height:
[tex]30000=18\times 25 \times h\\\\30000=450h\\\\h=\frac{30000}{450}[/tex]
h = 66.7 centimeters.
