<u>A cross section parallel to the base is a square measuring 4 cm by 4 cm
</u>
<u>Step-by-step explanation:</u>
Here we have to select the correct statement regarding a cross section of the cube :
<u>A cross section parallel to the base is a square measuring 4 cm by 4 cm
:</u>
Since , every side of a cube is same . Any cross section of a cube must be parallel to a square base . Hence, correct statement .
<u>A cross section parallel to the base is a rectangle measuring 4 cm by greater than 4 cm
:</u>
Since , every side of a cube is same . Any cross section of a cube must be parallel to a square base . Here, base is rectangle . We don't have a rectangle base in cube . Not correct statement.
<u>A cross section perpendicular to the base through the midpoints of opposite sides is a rectangle measuring 2 cm by 4 cm:</u>
Since , every side of a cube is same . Any cross section of a cube must be parallel to a square base . Here, base should be square not rectangle . So , Not correct statement.
Consider this option/solution.
P.S. The method of solution is Gauss' method.
