This zigzag crystal vase has a height of 10 inches. The cross-sections parallel to the base are always rectangles that are 6 inches wide by 3 inches long.

1. If we assume the crystal itself has no thickness, what would be the volume of the vase?
2. The crystal is actually half an inch thick on each of the sides and on the bottom. Approximately how much space is contained within the vase? Explain or show your reasoning.

List two solids for which the formula \(V=Bh\) applies and two for which \(V=Bh\) does not apply.

Each small square represents 1 square centimeter.

1. Sketch and label the solid formed by rotating this two-dimensional figure around the vertical axis shown.

   

2. What is the volume of this solid?

A solid has a volume of 2 cubic units and a surface area of 10 square units. The solid is dilated, and the image has volume 128 cubic units. What is the surface area of the image?

A solid with surface area 50 square units is dilated by a scale factor of \(k\) to obtain a solid with surface area 200 square units. Find the value of \(k\).

Imagine slicing a solid into parallel cross-sections. Name 2 figures that have congruent cross-sections in a particular direction.
