Volume is cubed. If the dimensions are doubled, cube the scale factor:
2^3 = 8
The volume will increase by a scale of 8.
The new volume would be 97 x 8 = 776 ft^3

10% of 200 is 20if you subtract 20 from 200 then you have to do it 8 times to get below 50
#1) 200-20=180
#2) 180-20=160
#3) 160-20=140
#4) 140-20=120
#5) 120-20=100
#6) 100-20=80
#7) 80-20=60
#8) 60-20=40
Maybe 120-130
As it’s more than 90 but slightly less than 135
Consider the suggested option:
1) if in 20 gr. of 50% solution given, then pure salt in this mix is 0.5*20=10 gr., and pure water is 0.5*20=10 gr.
2) after Maya added 5 gr. pure salt is 10+5=15 gr. Total mass of mix is 15(pure salt)+10(pure water)=25 gr.
3) new solution is 15/25=0.6 or 60%.
Answer: 25 gr. of 60% salt solution.
If you would like to simplify (5 * p^2 - 3) + (2 * p^2 - 3 * p^3), you can calculate this using the following steps:
(5 * p^2 - 3) + (2 * p^2 - 3 * p^3) = 5 * p^2 - 3 + 2 * p^2 - 3 * p^3 = - 3 * p^3 + 7 * p^2 - 3
The correct result would be - 3 * p^3 + 7 * p^2 - 3.
