Answer:
-1/2
Step-by-step explanation:
The vol. of a cube of side length s is V=s^3.
So, if the side length is 5a+4b, then the volume of the cube is
V(a, b) = (5a+4b)^3. This could, of course, be expanded, using the binomial theorem, but there's no point in doing so.
That’s the equation for pi, but the simplified fraction is 22/3 (please mark brainliest)
