Answer:

C. 35 square centimeters

Explanation:

What we need for this question:

The edges of a cube are 5 centimeters each.

The face diagonal is about 7 centimeters. (actually 7.0710678118655 cm)

To find the cross sectional area here, multiply 5 cm by 7 cm.

5 cm * 7 cm

35 cm² is your final answer, so C is the answer.
