ok you need formula for surface area.
SA = πrh+2πr^2
Plug in 25 and 5
SA = 2π(5)(25)+2π(5)^2
SA = 10pi*25 + 2pi(25)
SA = 250pi + 50pi
SA = 300pi
Hope this helps :)

Answer:
<h2>8 times greater</h2>
Step-by-step explanation:
The formula of a volume of a cube:

a - edge length
-----------------------------------
The edge length of cube B is a.
The edge length of cube A is 2a.
Calculate the volumes:

How many times greater is the volume of the cube A than the volume of cube B?
Make the quotient:

1. Divide both sides by 2
2. Add 16 to each side
Answer x > -2
