Answer 2

$\green{\huge{\underline{\underline{Answer:-}}}}$

Given:

Side of cube = 1.5 + 2.1 = 3.6m

To find:

Lateral surface area of cube = ?

Total surface area of cube = ?

Solution:

Lateral surface of cube = 4× side²

$\\ = 4 \times \: (3.6) {}^{2} \\ \\ = 12.96 \times 4 \\ \\ = 51.84 \: m {}^{2}$

Therefore, lateral surface area of cube is 51.84 m²

Total surface area of cube = 6 × side ²

= 6 × (3.6)²

= 6 × 12.96

= 77.76 m²

Therefore, surface area of cube is 77.76m²
