Question

Find the length of the side of a cube whose surface area is $1536c{m}^2$.

• A. $0.16m$
• B. $16cm$
• C. $1.6m$
• D. $160cm$

Answer 1

Answer: (A), (B)

The correct options are
A

$0.16m$

B

$16cm$

The surface area of a cube is equal to $6a^2$.

So, $6a^2=1536$

$a^2=256$

$a=\pm 16$

Since length can't be negative, $a=16cm$

In $m$, it is equal to $0.16m$.
