for the right side

if the SA=14 and the size is increased 5 times that means that the height is now 5 times bigger and the radius is 5x bigger so now we must calculate for the new cylinder is 5*5 bigger which is 25 times bigger similar if you took radius =1 and height =5 you get that its 37.7 but then increase to r=5 h=25 you get 942.48 which is 25 times bigger so for this you do 14*25= 350m^2.

As for the volume it is to the power of 3 so what we do is 5^3=125 times bigger. Which means the volume is 125 times bigger than 29 which is 3625m^3

left side: factor of 7:6 so 7/13 is how much we increase it by

which means we have 5832 and it says that its a cube so we know that all the sides must be equal which means our cube is 18*18*18. Then we increase it by 7/13*18=9.7 then we plug into our formulas to solve which is 912.673m^3 and for the area we get 564.54m^2 for volume i did x^3 and for area i did 6x^2
