Question

Find the side of a cube whose total surface area is numerically twice its volume.​

Answer 1

Answer:

side=3

Step-by-step explanation:

Let side = a

$total \: surface \: area = 6 {a}^{2}$

$volume = {a}^{3}$

from the given condition we have

$6 {a}^{2} = 2 {a}^{3}$

solving this we get a = 3
