Let's break down the clues step by step to determine the number.

Clue 1: I have six digits.

• The number is six digits long, so it is in the form: $\_ \_ \_ \_ \_ \_$.

Clue 2: The value of my tens is 6 x 10.

• This means the value in the tens place is 60, so the digit in the tens place is 6.

$\_ \_ \_ \_ 6 \_$

Clue 3: I have fewer than 5 hundreds but more than 2 hundreds.

• The hundreds digit is between 3 and 4 (inclusive). So the digit in the hundreds place is either 3 or 4.

$\_ \_ \_ 3/4 6 \_$

Clue 4: I have 3 more ten thousands than I have tens.

• The tens digit is 6 (from Clue 2). So the ten thousands digit must be 6 + 3 = 9.

$\_ 9 \_ 3/4 6 \_$

Clue 5: The digit in my hundred thousands place is 3 times the digit in my hundreds place.

• If the hundreds digit is 3, then the hundred thousands digit must be 3 × 3 = 9.
• If the hundreds digit is 4, then the hundred thousands digit must be 3 × 4 = 12, but this is impossible since a digit must be between 0 and 9.
• Therefore, the hundreds digit must be 3, and the hundred thousands digit is 9.

$9 9 \_ 3 6 \_$

Clue 6: The value of my thousands is 10 times as much as the value of my hundreds.

• The value in the hundreds place is 3, so the value in the thousands place must be 30, meaning the thousands digit is 0.

$9 9 0 3 6 \_$

Clue 7: My ones digit can be represented by a single ones block.

• This means the ones digit is 1.

$9 9 0 3 6 1$

Final Answer:

The number is 990361.
