The World Cup Trophy Caper

The stadium lights are blazing and millions of fans are cheering in the stands, but behind the scenes, disaster has struck! Just minutes before kickoff, the legendary World Cup Trophy was snatched from its high-security display vault. The Head Referee found only a grass-stained soccer sock left in its place. As the lead youth detective, you must analyze the clues, track down the rogue player, and recover the trophy before the final whistle blows!

Clue 1

Pythagorean theorem

Security cameras captured the suspect escaping diagonally across the field. To find the exact distance of their escape path, the security team uses the pitch lines to calculate the hypotenuse.

Clue 5

Square roots — the last clue

The stadium's motion detectors cover a perfectly square security zone around the VIP entrance. Finding the square root of this guarded area helps us pinpoint where the suspect disabled the alarm.

First solve each problem. Then find each answer in the list below and cross that sentence out. One sentence will be left — that's exactly what the villain did!

Step 1 — solve these

sqrt(16) = ?

sqrt(9) = ?

sqrt(144) = ?

sqrt(121) = ?

sqrt(36) = ?

sqrt(4) = ?

sqrt(25) = ?

sqrt(64) = ?

sqrt(1) = ?

sqrt(49) = ?

sqrt(100) = ?

Step 2 — cross out the sentence with each answer

1.The villain scores with a diving header, then escapes in dynasty knit footwear.

2.The villain scores with a diving header, then runs off in acro brand cleats.

3.The villain scores with a diving header, then speeds off wearing crown leather boots.

4.The villain scores with a diving header, then dashes away in bolt stripes shoes.

5.The villain crosses with a rabona pass, then flees the pitch in eclipse sole cleats.

6.The villain performs a flawless bicycle kick, then escapes in dynasty knit footwear.

7.The villain performs a flawless bicycle kick, then dashes away in bolt stripes shoes.

8.The villain strikes a knuckleball free kick, then flees the pitch in eclipse sole cleats.

9.The villain strikes a knuckleball free kick, then dashes away in bolt stripes shoes.

10.The villain crosses with a rabona pass, then runs off in acro brand cleats.

11.The villain strikes a knuckleball free kick, then speeds off wearing crown leather boots.

12.The villain performs a flawless bicycle kick, then runs off in acro brand cleats.
