Answer:
B. The quilt consisted of 1,008.
Step-by-step explanation:
You take the initial number of squares the quilt had, which was 126. If that number was repeated 8 times for the entire quilt you would have to take 126*8 and the answer would be 1,008.

<span>The rounded result is
4,000. If you just write "4,000", though, it's not clear whether there
are 1, 2, 3 or 4 significant figures, since trailing zeroes could be
significant (or not). For that reason, scientific notation is often
used. 4 × 10³ has one significant digit, 4.0 × 10³ has two, 4.00 × 10³
has three, and so on.
So, use either 4,000 or 4 × 10³, depending on what your teacher expects.</span>
438 has a three in the tens place :)
