Correct Answer - Option 2 : 4913 cu.cm

**Given:**

75% of T.S.A = 1300.5 sq.cm

**Formula used:**

T.S.A of cube = 6a^{2}

Volume of cube = a^{3}

**Calculation:**

Let the T.S.A be x

so, 3/4 × x = 1300.5

⇒ x = (1300.5 × 4)/3 = 1734 sq.cm

6a^{2} = 1734

⇒ a^{2} = 289

⇒ a = 17 cm

Volume = 17^{3} = 4913 cu.cm

**∴ The volume is 4913 cu.cm**
