Step-by-step explanation:
I wish you could've provided the illustration so I would know
what the x is
but assuming the x is equal to one surface then,
Perimeter of the cube (P) = 6 × Area of the square
P = 6 × A
P = 48
A = 48 ÷ 6
A = 8
if x indicates the side of the square then,
A = S²
A = 8
S² = 8
S = √8
S = 2√2
