A small block is placed along a $10 \mathrm{~cm}$ ruler. Which of the following is closest to the length of the block?
(A) $0.24 \mathrm{~cm}$
(B) $4.4 \mathrm{~cm}$
(C) $2.4 \mathrm{~cm}$
(D) $3 \mathrm{~cm}$
(E) $24 \mathrm{~cm}$

Part B: Each correct answer is worth 6.
Since the left edge of the block is at the " 3 " on the ruler and the right edge of the block is between the " 5 " and " 6 ", then the length of the block is between 2 and 3 .

Looking at the possible choices, the only choice between 2 and 3 is (C) or $2.4 \mathrm{~cm}$.

(Looking again at the figure, the block appears to end roughly halfway between the "5" and the " 6 ", so $2.4 \mathrm{~cm}$ is reasonable.)

ANswer: (C)
