Hello there! So a cube has side lengths that are all equal and the formula for volume is l * w * h. If you raise the answer choices to the 3rd power, you see that 9³ is equivalent to 729, which is the volume we're looking for. The length of the side of the cube is 9 ft. The answer is B: 9 ft.
It will take 7.666666667 hours ( or so ) to travel from Boston to Washington, so if he leaves at 7:30 he will arrive at ( not including the decimal ) 2:30 pm.
Hope this helps, if not, comment below please!!!

Step-by-step explanation:
We want to the equation in an exact form
M(x, y) dx + N(x, y) dy = 0.
xy² dy/dx = y³− x³
Cross multiply
Then,
xy²dy=(y³-x³)dx
xy²dy - (y³-x³)dx = 0
xy²dy + (x³-y³)dx=0
Therefore,
(x³-y³)dx + xy²dy=0
Can only be an exact equation if and only if
dM/dy=dN/dx
From the equation
M=(x³-y³)
Then, dM/dy=-3y²
Also, N=xy²
dN/dx=y²
Since dM/dy ≠ dN/dx
Then it is not an examct equation and we can say
M≠(x³-y³)
And
N≠(xy²)
