Whoever answers first i will mark as brainiest
bija089 [108]

Answer:

B. 7 inches

Step-by-step explanation:

The surface area of a cube is denoted by: A = 6s², where s is the side length.

Here, we know that A = 294 in², so plug this into the equation to solve for s:

A = 6s²

294 = 6s²

s² = 49

s = √49 = 7

The answer is thus B, 7 inches.
