Answer:
8
Step-by-step explanation:
The term 8x is a product (as is any term). It is the product of a constant coefficient (8) and a variable (x). The "coefficient" is the multiplier of the variable of interest, so is 8 in this term.
_____
The word "coefficient" is often used to refer to the constant multiplier in any term. For example, in the term 6xy, if we just ask for the coefficient, we are interested in the value 6.
On the other hand, if we ask for the coefficient of y in that term, we expect to be told it is <em>6x</em>. That is, the "coefficient" is the multiplier of the specified variable or constellation of variables.

Step-by-step explanation:
There are none. "Square foot" is a unit of area, not volume.
Square feet are flat, and can't hold water.
If you meant to ask about 161.25 CUBIC feet, I can help you there:
(161.25 ft³) x (1,728 in³/ft³) x (1 gallon/231 in³) = <u>1,206.234 gallons</u> (rounded)
