How many times larger is the surface area of the larger prism compared to the surface area of the smaller prism? 9 6 3 2

Three times larger.

This is because you have to multiply 2m (the smaller prism) by three to get 6m (on the bigger prism), then you will find that if you multiply the rest of the numbers (on the smaller prism) by three you will get the exact numbers that are on the big prism. Hope this helps!

3 is wrong because is says surface area of the smaller and larger and the surface area of the small one is 10m^2 and the surface area of the larger one is 90m^2 so it would be 9 times larger.
Hope I helped!
