Delayed checkpoint: check retention: original cases with explanations after your first response.

Paper packet. Every task here also exists on screen, where it is checked automatically; answers written on paper are not assessed by Nydus. When you are back at a device, enter your answers there.

1. What you will learn

Use the later cone comparison, rhombus and interior-cube tasks to check whether dimensional relationships are retained. Identify the requested measure before using any remembered formula.

2. Practice

A cone and cylinder have equal radius and height. If the cone's volume is 35, what is the cylinder's volume? Use V_cone=pi r squared h/3.

Answer:

3. Practice

A 6 by 6 by 6 cube is cut into unit cubes. How many unit cubes touch none of the original cube's faces?

Answer:

4. Practice
