300% change. 36/12. 100%=12, 12*3=36, therefore 100%*3=300%
Answer:
27
Step-by-step explanation:
Let the radius of the smaller sphere is x.
Then the radius of the larger sphere is 3x.
The volume of a sphere is given by
Hence, the volume of the smaller sphere is
And the volume of the larger sphere is
Divide both volumes, we get
Hence, the volume of the smaller sphere is 27 times smaller than the volume of the larger sphere.

Hi,
8 Pckts each has 500 g weight .Total weight would be 8*500=4000g
and she arranged them into 3 boxes.
assume those three boxes are X,Y,Z first,second,thrid respectively.
X+Y+Z=4000g--------------------1
then according to the statement first box is twice heavy as second one
means X=2Y----------------2
and thrid box is 60g heavier than second box.
Z=Y+60--------------------3
put those values in to eq 1
2Y+Y+Z=4000
3Y+Y+60=4000
4Y=4000-60
4Y=3940
Y=985
second box weight is 985 gram
