Cube Root 1113 = 10.36
Cube Root 53 = 3.76
The ratio is 10.36/3.76 = 2.76
Cube Root (21) = 2.76 to 3 places.
D <<<<<<<answer.
There is another way to do this (much better I think).
1113/53 = 21
A solid has 3 dimensions. Each dimension of the big solid will be k times bigger than the little one.
Therefore the volumes are related by a factor of cube root(large one ) to small one = cube root (21)
