Worked practice questions

A square tile has side 7 cm. Its area, 49, is called a:

  1. Square number
  2. Cube number
  3. Prime number
  4. Odd number
Show answer and solution

Correct answer: A. Square number

1. 49 is 7 multiplied by itself. 2. Numbers like 1, 4, 9, 16, 25 are of this kind. 3. They are square numbers. _Source: syllabus Mathematics, Chapter 6, Squares and Square Roots._

32 lies between 25 and 36, so it is:

  1. A perfect cube
  2. Not a square
  3. A square of 5.5
  4. A square of 6
Show answer and solution

Correct answer: B. Not a square

1. 25 is 5 squared and 36 is 6 squared. 2. No natural number lies between 5 and 6. 3. So 32 is not a square number. _Source: syllabus Mathematics, Chapter 6, Squares and Square Roots._

Which digit can never be the units digit of a square number?

  1. 7
  2. 1
  3. 6
  4. 9
Show answer and solution

Correct answer: A. 7

1. Squares end in 0, 1, 4, 5, 6 or 9. 2. They never end in 2, 3, 7 or 8. 3. So 7 is impossible. _Source: syllabus Mathematics, Chapter 6, Squares and Square Roots._
