Question

The right rectangular prism will be sliced perpendicular to its base along the dashed line. Select from the drop-down menus to correctly describe the cross section formed by the slice. The cross section is a square with an area of A. 36, B. 48, C. 72, D. 96

Answer 1

The Cross section takes the shape of the end. If it was slicing across horizantaly than it would be a rectangle. The section takes the shape of a rectangle.

Answer 2

The cross section is a rectangle with an area 48 cm². Option B is correct.

Explanation:

It is given that the dashed line represents the cross section.

From the given figure it is clear that the two consecutive sides of cross section are 6 cm and 8 cm.

Length of both sides are difference, so it is a rectangle.

The area of rectangle is

`A=length* breadth`

`A=6* 8`

`A=48`

The area of the cross section is 48 cm².

Therefore option B is correct.
