Diagonal = s root 3 where s= side
Therefore side = 12cm
Surface Area = 6s^2 = 6(12)^2 = 6(144) = 864 cm^2
Volume = s^3 = 12^3 = 1728 cm^3
answer
The earth rotates once every 23 hours, 56 minutes and 4.09053 seconds, called the sidereal period, and its circumference is roughly 40,075 kilometers. Thus, the surface of the earth at the equator moves at a speed of 460 meters per second--or roughly 1,000 miles per hour
