Given:
The volume V of the cube is 216 mm3.
The number of faces of the cube is 6, we find the area of one face of the figure:
S = V: 6 = 216: 6 = 36 mm3.
All edges of the cube are equal to each other, we calculate the length of one edge by the formula a = √S:
a = √S = √36 = 6 millimeters.
Answer: the length of the edge of the cube is 6 millimeters.
