The right rectangular prism will be sliced parallel to its base along the dashed line. Select from the drop-down menus to correctly describe the cross section formed by the slice.

Answer:
The Cross Section is an Rectangle with area of 12 cm².
Step-by-step explanation:
We are given with a Rectangular prism that is a Cuboid.
Dimensions of Prism are the following,
length, l = 4 cm
width, w = 3 cm
height, h = 7 cm
We need to find the shape of the cross section and area of the cross section.
Since Prism is sliced parallel to base then shape of the cross section is same as the shape of the base that is RECTANGLE.
Area of Cross Section = Area of Base
= Area of Rectangle
= length × width
= 4 × 3
= 12 cm²
Therefore, The Cross Section is an Rectangle with area of 12 cm².
