Answer:

The approximate area of the cross section passing through the diagonals of opposite faces of this cube is:

C. 35 square centimeters.

Step-by-step explanation:

When you think in the cross section passing through the diagonals of opposite faces of the cube given, you can see that it's a rectangle with long = 7 centimeters and wide = 5 centimeters ( the measure of an edge of the cube), having this, you can calculate the area:

Area of a rectangle = long * wide
Area of a rectangle = 7 cm * 5 cm
Area of a rectangle = 35 cm^2 or 35 square centimeters
