Question

Q-1 [A] Fill in the blanks.

1) Volume of cube is 729 m³, it’s edge is ________

2) The value of 10-2=________

3) (51)² –(49)²= __________

4) A solid figure with only 1 vertex is a ____________

5) 6n/6−2=63∴ n= _______​

Answer 1

Answer:

1 ) Volume of Cube ( V ) = 729

Side = ?

Volume = a³ = 729

Side = 3√ 729

Hence

S = 9 m

2 ) Value of 10 - 2

10

2

---

8

----

3 ) ( 51)² – (49)²

2601 - 2401

200

4 ) A solid figure with only 1 vertex is Cone .

5 ) 6n / 6 - 2 = 63

6n - 3 / 6 = 63

6n - 3 = 63 × 6

6n = 378 + 3

6n = 381

n = 381 / 6

n = 63.5
