Answer:
7 and 11
Explanation:
The amount of sand on the beaches can be found using this formula:
volume (m3) = length (m) × width (m) × depth (m)
(6 × 108 m) × 60 m × 20 m = 7 × 1011 m3
Therefore, there would be a total of 7 × 1011 cubic meters of sand on the beaches.
No chemical because, its changeing the stuff
For alpha and beta decay it does because the proton number changes.
During gamma, there is no change of identity, just energy
