9.9 x 10 cubed is equal to 9,900.
99 x 10 - 99 x 9 = 99(1 x 10 - 1 x 9) = 99(10 - 9) = 99(1) =99

Any two digit nuber from 10-99 can be squared or cubed.
10 x 10 x 10
9 cubed = 729 = (7 x 10^2) + (2 x 10^1) + (9 x 10^0)
15 cubed = 15^3 or (3 x 10^3) + (3 x 10^2) + (7 x 10^1) + (5 x 10^0)
9 cubed = 729 = (7 x 100) + (2 x 10) + (9 x 1)
10 x 10 x 10 for one example...
mass = density x volume Mass = 5 grams per centimeter cubed x 10 centimeters cubed = 50 grams
Find the reciprocal: 9/10
9 cubed is equal to 729 or (7 x 100) + (2 x 10) + (9 x 1)
7 cubed is equal to 343 or (3 x 100) + (4 x 10) + (3 x 1)
