What is the volume of a cube whose one side is 5cm​

125 cm^3

Step-by-step explanation:

The volume of a cube is given by length*width*height. In a cube, all sides are the same. Therefore, you can put in (5cm)*(5cm)*(5cm) and get 125 cm^3

call the larger triangle abc

then the smaller triangle cde is similar to abc (all angles are equal, aaa).  

ab is the side that is 36, and we wish to find de, the side corresponding to ab

area_cde = area_abc - area_cde --> area_abc / area_cde = 2

let x=length of de

ratio of areas = (ratio of sides)^2

+2+=+1296%2fx%5e2+

++x%5e2+=+1296%2f2+=+648+
