Cut 1 cubic meter cube block into 1 cubic decimeter cube block. If these blocks are arranged in a row, they are () long A. 1km B. 100m C. 100m D. 1000M

Cut 1 cubic meter cube block into 1 cubic decimeter cube block. If these blocks are arranged in a row, they are () long A. 1km B. 100m C. 100m D. 1000M

1 cubic meter = 1000 cubic decimeter, so: 1000 △ 1 = 1000 (pieces), the edge length of a small cube of 1 cubic decimeter is 1 decimeter; then the total length is 1 × 1000 = 1000 (decimeter) = 100 meters
