Answer 2

Let the side be = $(l)$ cm

TSA of cube = $(6l^2)$

LSA of cube = $(4l^2)$

As per condition,

$TSA - LSA = 392$ cm²

⇒ $6l^2 - 4l^2 = 392$

⇒ $2l^2 = 392$

⇒ $l^2 = 196$ cm²

∵ TSA = $(6l^2)$,

∴ $6l^2 = 196 \times 6$ cm²

⇒ $TSA = 1176$ cm².

Henceforth, the TSA of the cube is 1176 cm².
