Applications on the real numbers
Area = L2 , Volume = L3 , Lateral area = 4 × A
L = perimeter ÷ 4
Total area = 6 × A ,
L = Sum of edges ÷ 12 ,
L = v??
L = ?v? ??
Example (1):
A cube with volume 125??????, find its total area and its lateral area.
Side = ?v? ?????? = ?? ????
Total area = 5 x 5 x 6 = 150 ??????
Lateral area = 5 x 5 x 4 = 100 ??????
