For this case we must propose a linear equation.

Let "x" be the variable that represents the unknown number.

So, we have:

2x: Represents twice the number

2x = 1: Represents that twice the number is equal to one.

We clear the value of "x":

We divide between "2" on both sides of the equation:

\frac {2x} {2} = \frac {1} {2}\\x = \frac {1} {2}

Answer:

x = \frac {1} {2}

I believe it would be 9,261 inches of water to fill the new cube.


To find the maximum capacity of a cube you have to multiply s*s*s (each s stands for one of its sides)

The side length happens to be 7. 7 times 7 times 7 is 343. If we triple that length now it’ll be 21. Multiply 21 by 21 by 21 it’ll give you 9,261 inches

3(n-8)=2n-2

3n-24=2n-2

Subtract 2n from both sides to get

n-24=-2

Adding 24 to both sides gives you

n=22. The number therefore is 22. Hope this helps!!!
