Count the blocks write the total number.

The correct answer is: 36

In the question there is a picture of some blocks from that picture we have to find the number of blocks present in the that picture.
Step 1: Count the 10s blocks.
Starting the counting from 1 we can say that there are 3 tens blocks.
Step 2: Count the 1s blocks.
Starting the counting from 1 we can say that there are 6 ones blocks.
Step 3: Add the number of 10s and 1s blocks.
30+6=36
So, there are 36 blocks in the given picture.
Therefore, the correct option is a, i.e., 36.
