The dimensions of a rectangular parallelepiped are 10 cm, 7 cm and 5 cm. find the area of the smaller face.

Let’s first compare the lengths of measurements of this rectangular parallelepiped presented in this task, in order to determine the area of which face we will need to calculate:

5 <7 <10.

Obviously, the smallest edge will have the smallest size, in this case it is 5 centimeters and 7 centimeters.

Let’s calculate what the face area of a rectangular parallelepiped with dimensions of 5 centimeters and 7 centimeters will be:

7 * 5 = 35.

Answer: The area of the smaller edge is 35 cm2.
