Unit Description

This unit we learned about area and perimeter, surface area, and volume. To find perimeter and area we used bumper car floor plans, to also find perimeter and area we used storm shelter floor plans. To find surface we used nets, finally to find volume we used box and centimeter cubes.

What is perimeter?

Perimeter is the continuous line forming the boundary of a closed geometric figure. Perimeter is measured in units.
