Question

Find the total surface area of the cube whose volume is 612cm square?​

Answer 1

Step-by-step explanation:

total surface area of cube; 6 a ^2

so'

6 multiply (612)^2

now you do it

Answer 2

Correct Question:

Find the total surface area of the cube whose volume is 512 cm cube ?

Answer:

$\bold\red{384{cm}^{2}}$

Step-by-step explanation:

It is being Given that,

A cube having volume $512{cm}^{3}$

Let the side of cube be 'a'.

Now,

We know that, volume,

V of cube = ${a}^{3}$

$=>{a}^{3}=512$

$=>{a}^{3}={8}^{3}$

$=>a=8\:cm$

Therefore, side of cube = 8 cm

Now, we know that,

Total surface area,

$S=6{a}^{2}$

$=>S=6×{8}^{2}$

$=>S=6×64$

$=>S=384{cm}^{2}$

Hence,

Total surface area of cube is $\bold{384{cm}^{2}}$
