You can put this solution on YOUR website!
Let y = width.
Let h = the extra height beyond 25 cm to reach complete height.
First Part, unknown volume, v = this unknown volume; v=46%2Ay%2A25.

Second Part, known volume, 12000 cubic centimeters.
45%2Ay%2A%2825%2Bh%29=12000.

Not enough given information to find y.

With a bit more work,
45%2Ay%2A25%2B45%2Ay%2Ah=12000
45y%2825%2Bh%29=12000
y=12000%2F%2845%2825%2Bh%29%29
But still need more information for a value.
