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 <u>equal base length</u>, 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 <u>equal side lengths</u>, 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
There the cross section will be a rectangle which measures
