For this case we have that by definition, the volume of a cube is given by:

Where:
l: It's the side of the cube
According to the statement we have:

Substituting we have:

Thus, the volume of the cube is 
ANswer:
The volume of the cube is 
Answer:
-1
Step-by-step explanation:
two points (4,0), (0,4)
slope=(y2-y1)/(x2-x1)=(4-0)/(0-4)=-1
Answer:
1/2
Step-by-step explanation:
(2,1)(4,2)
x1-y1/x2-y2
slope:m=1/2
