A cuboid would fit the given description
No, not all cross-section shapes that are parallel or perpendicular to one of the bases of a solid are necessarily the same. The shape of the cross-section depends on the geometry of the solid. For example, in a cylinder, the cross-sections parallel to the bases are circular, while in a prism, they may be polygonal. Each solid can produce different cross-sectional shapes based on its specific dimensions and angles.
square
A right angle triangle.
A hexagon.
trapezoid
a cross
shape no pairs of perpendicular sides
A rhombus has parallel lines but no perpendicular lines.
The normal strain is a deformation caused by normal forces such as Tension or Compression that act perpendicular to the cross-sectional area, while the shear strain is a deformation obtained from forces acting parallel or tangential to the cross-sectional area.

To calculate the cross-sectional area of a shape, you need to determine the shape of the cross-section first (e.g., square, circle, triangle). Then, use the appropriate formula for that shape. For example, the formula for the cross-sectional area of a square is side length squared, for a circle it is pi times the radius squared, and for a triangle it is base times height divided by 2. Finally, plug in the given dimensions into the formula to calculate the cross-sectional area.
Hexagon.
If you slice a wire cleanly and then look at the cut end, you see a little circle at the end. The area of that circle is the "cross-sectional area" of the wire. The larger that area is, the lower the DC resistance of the wire is.
False. Every cross-sectional shape of a cone is not congruent.
Trapizium
A right angle triangle.
A hexagon.
