He fish tank pictured can hold up to 1004.5 cubic ft of water. what is the length of the fish tank? length of fish tank is 7ft

Since you repeated length two times, I'm assuming you are finding the width of the tank. The cubic feet (volume) = The length of the tank (length) * the width of the tank (width).

Let v = the cubic feet

Let l = length of the tank

Let w = width of the tank

So, v = l*w, this is equal to the first sentence I put, but just replaced with variables.

Next, determine given values.

v = 1004.5 cubic feet

l = 7 feet

w = ? <- this is what we need to find.

Substitute in all the known values.

1004.5 = 7 * w ( the variable w is used for undetermined width )

Divide by 7 on both sides to get x alone in the form of w = #.

w = 143.5

The width of the tank is 143.5 feet.

6,250

step-by-step explanation:

to get the area, multiply 360 by 160.(57,600)

to find out how many bags of fertilizer it will take, first figure out how many square feet one bag can hold. divide 1000 by 8(125) to get the unit rate(how many square feet one pound of fertilizer can hold)and multiply it by 50(6250). if i haven't made a mistake, that is the answer.

the 3rd on is correct
