The side view drawing is a two-dimensional

is still an accurate drawing of the new
figure.

2. Build Understanding
The top view of a cube looks the same as the top view of the square pyramid.
However, while you can stack other solids on top of a cube (which has a flat top), you cannot stack solids on
top of a square pyramid. The top of a square pyramid is actually a raised point. Nothing can be stacked on
top of a square pyramid.
Explain that this always a consideration when stacking items, such as boxes and cans in a supermarket
display, and that a flat top is required for stacking.
