| April 10, 2021 | education
The volume of a cube is calculated by the formula: V = a ^ 3, where a is the edge of the cube. Since, according to the condition of the problem, the volume of the cube is 125 dm3, we will find the length of the edge of the cube:
125 = a ^ 3;
5 ^ 3 = a ^ 3;
a = 5 dm.
A cube has 6 faces, each of which is a square. The area of the square is found by the formula: S = a ^ 2.
Thus, the area of one face of a cube is:
S = 5 ^ 2 = 25 dm2.
Answer: 25 dm2.
