If the row of 11 squares is built from left to right, the first square requires 4 toothpicks and each subsequent square requires 3 additional toothpicks. These 3 toothpicks form the top edge, the right edge and the bottom edge. The left edge is formed by the right edge of the previous square.

Therefore, 11 squares require $4+10 \cdot 3=34$ toothpicks.

ANSWER: 34
