The volume of the second prism is 576 cubic centimeters. Since both prisms have the same height, I solved for the height using the data given with the first prism (I got 6 centimeters for the height). And then I calculated for the volume of the second prism.

Answer:
x = 
y =  
Jacobian value = 1/7
Step-by-step explanation:
Given data:
u = 2x -y 
v = 3x + 2y
solving the system for  x and  y in terms of u and v 
x = 
y =  
The value of the Jacobian =  1/7 ( solution attached below )
