Volume ratio = 1331/729 which is the cube of the linear scale factor.
To find the linear scale factor, let find the cubic root of the numerator & the denominator:
∛1331 = ∛11³ = 11
& ∛729 = ∛9³ = 9
So the linear scale is 11/9 ==> then the ratio of their surface area will be:
11²/9² ==> 121/81.
Note, if you have a linear scale, then the surface will be the square othis scale & the volume will be the cube of the linear scale
60 min in one hour so 60+60+30=150.
150 divided 50 mins = 3 days (50+50+50=150)
7 , it’s x = 12 1/3, or in decimal form, 12.33. And at 8, it’s x = -6/11, or in decimal form, -0.54
