270=2b + a
420=2a + 3c (you have to use trial and error for this)

B = 120
A = 30
C = 120

Just to check
270 = (2x120) + 30
420 = (2x30) + (3x120)

Answer: 15 inches is the height of Keisha's fish tank.

Step-by-step explanation: Basically, multiply your length x width, which is 12 x 10. 12 x 10 = 120.

Next, divide 1800 by 120.

1800 divided by 120 is 15.

So, 15 inches is the height of the fish tank.
