Answer 1

Answer:

See explanation

Step-by-step explanation:

The question is incomplete; So, I will solve the question generally.

Assume the following;

$l \to length$

$w \to width$

$h \to height$

Since the water level must be 2 inches below the tank height, the water height is:

$H \to h - 2$

So, the water volume is:

$Volume = l * w * H$

$Volume = l * w * (h - 2)$

Hence, the expression is:

$Volume = l * w * (h - 2)$

Assume that:

$l = 5; w = 10; h = 8$

The volume becomes:

$Volume = 5 * 10 * (8 - 2)$

$Volume = 5 * 10 * 6$

$Volume = 300$ cubic units
