Answer:
we know that, Volume of cube=a³
Let volume of 1st cube be 2x with side a and other be x with side A (according to given ratio)
Step-by-step explanation:
ATQ: 2x=a³ and, x=A³
a=³√2x and, A=x
we know that, surface area of cube is 6a²
Thus, surface area of 1st cube = 6(³√2x)²
= 6³√4x²
Surface area of 2nd cube=6(x)²=6x²
Ratio of S.A=(6³√4x²)÷(6x²)
Ratio of S.A=³√4:1

Assuming the can is a cylinder set up the equation V=pi(r)^2h
215=pi(r)^2(7.5)
r^2=9.1248
r=3.021
What’s the question thought-
1/6? Because it’s only one piece of the spinner
Sorry I can't help you :(
