Answer 2

Answer:

Step-by-step explanation:

1》given,

Side=6.8m or 680 cm

Surface area=6×(side×side)

6×462400cm=2774400cm square

Or 2774400÷10000=277.44m square

2》given,

Side=5.5m or 550cm

Surface area=6×(550×550)

6×302500cm=1815000cm square

Or 1815000÷10000=181.5m square

[You can do it without converting unit of side]
