A cube with 4 centimeter sides.

A cross section parallel to the base is a square measuring 4 cm by 4 cm.

A cross section parallel to the base is a rectangle measuring 4 cm by greater than 4 cm.

A cross section perpendicular to the base through the midpoints of opposite sides is a rectangle measuring 2 cm by 4 cm.

A cross section perpendicular to the base through the midpoints of opposite sides is a square measuring 4 cm by 4 cm.

A cross section that passes through the entire bottom front edge and the entire top back edge is a rectangle measuring 4 cm by greater than 4 cm.

Answer:

B,E and F

Step-by-step explanation:

  • (B)A cross section parallel to the base is a square measuring 4 cm by 4 cm.

Since a cube has equal base length, any cross section parallel to the base will also have an equal base length.

  • (E)A cross section perpendicular to the base through the midpoints of opposite sides is a square measuring 4 cm by 4 cm.

Since a cube has equal side lengths, any cross section parallel to the side will also have an equal base length.

  • (F)A cross section that passes through the entire bottom front edge and the entire top back edge is a rectangle measuring 4 cm by greater than 4 cm.

Using Pythagoras Theorem

[tex]4^2+4^2=4\sqrt{2}>4[/tex]

There the cross section will be a rectangle which measures [tex]4\sqrt{2}\:cm\:by\:4\:cm[/tex]
