Answer:
If M is the midpoint, then LM = MN
3x - 2= 2x +1
x = 3
So LM = 3x - 2 = 9 -2 = 7
LM = 7
Volume of Original Prism = base area * Height = 3 * 4 = 12
After dilation factor = 12 * 3/2 = 6 * 3 = 18
In short, Your Answer would be 18 m³
Hope this helps!
The sign of the product would be the postitive sign because all three integers have the same sign.
