the first one is -6, 8 second is 0,8!
The surface area increases by a factor of 4. 2^2= 4.
The area of the long side is 3×1= 3cm^2 on the small prism.
The area of the long side is 6×2= 12cm^2 on the large prism.
12/3= 4.
Where is the angle? How can I solve this without the problem?
Difference=subtract sum=add. just answering so you don't waste points :-)
