tion passing through the diagonal of opposite faces of this cube
1 answer:
Answer:
The approximate area is 35 square centimeters
Step-by-step explanation:
we know that
The cross section passing through the diagonal of opposite faces of the cube is a rectangle
so
the approximate area is equal to

where
b is the diagonal of a face
h is the length side of the cube
we have

substitute
