The number of hollow blocks in 20 meters depends on the size of the blocks. Standard hollow blocks typically measure about 40 cm x 20 cm x 20 cm. If you were to line them up along a 20-meter distance, you would need approximately 50 blocks, as 20 meters equals 2000 cm, and 2000 cm divided by 40 cm (the length of one block) equals 50.

20 square yards is 16.7 square meters.
4*5 = 20 square meters
18.58 square meters.
10 cm = 0.1 meter 20 cm = 0.2 meter Each block covers (0.1 x 0.2) = 0.02 square meter. To cover 12 square meters, you need 12/0.02 = 600 blocks.

In New York City, a typical block in Manhattan is approximately 1/20 of a mile long, which translates to about 80 meters. Therefore, there are roughly 12 to 13 blocks in a kilometer. However, blocks can vary in size across different boroughs and neighborhoods.
