Answer:
SA = 2400 cm²
Step-by-step explanation:
SA of a cube = S² x 6 (the number of its faces)
SA = 20² x 6
SA = 400 x 6
SA = 2400 cm²
According to the conversion table we know,
1 meter = 100cm
This means if we need to convert meters to centimeters, we need to multiply by 100
Or
If we need to convert from centimeters to meters, we need to divide by 100.
Here the length of the wire needed to wrap 175 bundles = 2975 cm.
Now as we need to convert it to meters.
We need to divide this by 100.
We get
2975/100= 29.75
So 2975 cm = 29.75 m
Option D) is the right answer
126 divided by 7 equals 18
18 m
