62.5% of 56 is 35
Divide 35 and 56:

Convert the decimal to a percentage:
The answer is x=1. I showed my work in the screenshot provided
22.4/4 = 5.6 cm
5.6^2 = 31.36 cm^2 per side
Since the later surface area only counts for 4/6 sides on the cube, (31.36)(4) = 125.44 cm^2
Answer:

Second divide by a getting b³=3S/a
Third take the cube root of both sides getting the cube root of 3S/a
