Question

This is wrong can someone help

Answer 1

Raising those numbers to the tenth power is wrong.
For example 9 to the 10th power is 3,486,784,401 - a huge number.


To find the surface area of a RECTANGULAR prism, you would need the area of all 6 rectangular faces.  
You must calculate
height * width *2
height * length * 2
width * length * 2

Then you would add these 3 figures.

Another problem?  You need the WIDTH of the prism which is NOT given.
