Advanced Math practice question

Answer: 3

s²(s + 2) = 45. Trying s = 3: 9 × 5 = 45. ✓ (s = 2 gives 16 and s = 4 gives 96, so 3 is the only positive solution.)

Common wrong answers

If you answered 5

5 is the height, s + 2.

If you answered 45

45 is the volume.

If you answered 6.7

6.7 is √45, treating the volume as s² alone.
