Cube wall

The perimeter of one cube wall is 120 meters. Calculate the surface area and the body diagonal of this cube.

Result

S =  5400 m2
u =  51.962 m

Solution:

o=120 m a=o/4=120/4=30 m S1=a2=302=900 m2 S=6 S1=6 900=5400 m2o=120 \ \text{m} \ \\ a=o/4=120/4=30 \ \text{m} \ \\ S_{1}=a^2=30^2=900 \ \text{m}^2 \ \\ S=6 \cdot \ S_{1}=6 \cdot \ 900=5400 \ \text{m}^2
u=3 a=3 3030 351.961551.962 mu=\sqrt{ 3 } \cdot \ a=\sqrt{ 3 } \cdot \ 30 \doteq 30 \ \sqrt{ 3 } \doteq 51.9615 \doteq 51.962 \ \text{m}
