To check whether the statements are correct, we need to convert cm to mm.
surface area of a cube = 6 a²
294 cm² = 6 a²
294 cm² / 6 = a²
49 cm² = a²
√49 cm² = √a²
7cm = a
1 cm = 10 mm
7 cm = 70 mm
Surface area of a cube = 6a²
= 6 * (70mm)² = 6 * 4,900mm² = 29,400mm²
<span>B. The number representing the surface area would increase.
</span><span>E. The actual surface area would stay the same.</span>
