Answer:
The correct option is (A).
Step-by-step explanation:
The expression Carey is solving is:
Simplify the expression as follows:
So, in Carey's calculation the third step is incorrect.
Instead of 27 the three-fourth must be multiplied by 36 to get the correct answer.
Thus, the correct option is (A).
Volume of each sphere = 4/3πr^3 = 4/3π(0.01/2)^3 = 5.236 x 10^-7
Volume of the 1 million bubles in 1 sheet = 1,000,000(5.236 x 10^-7) = 0.5236
Volume of air contained in the bubbles of 2 sheets of bubble wrap = 2(0.5236) = 1.047 cubic meters.
The way u wrote it doesn't make sense
but u should combine like terms. then multiply regularly. hope this helps
