Question

The length of cuboid is two times of its breadth and 4 times of its height. If the volume of the cuboid is 64m³,find its total surface area.

Answer 1

Answer:

here answer is 16 cm square

Answer 2

Step-by-step explanation:

Answer:

TSA of cube is 96 m².

Step-by-step explanation:

Given :-

The lateral surface area of a cube is 64 m.

To find :-

Total surface area of cube.

Solution :-

Let the each side of cube be a m.

★Formula used :

${\boxed{\sf{CSA\:of\:cube=4a^2}}}$

CSAofcube=4a

2

According to the question,

4a² = 64

→ a² = 64/4

→ a² = 16

→ a = √16

→ a = 4

Each side of cube is 4 m.

★Formula used :

${\boxed{\sf{TSA\:of\:cube=6a^2}}}$

TSAofcube=6a

2

Total surface area of cube,

= 6a²

= 6×(4)² m²

= 6 × 16 m²

$\textbf{= 96 m²}$

Therefore, total surface area of cube is 96 m².
