## Unit Description

This unit is about surface area, perimeter, area and volume. We did a bumper car activity that helped us figure out the perimeter and the area of a bumper car floor plan. This helped us figure out how much material we need to fill the space. Then we did a storm shelter activity. We had to find the perimeter and the area of each floor plan. For surface area, we had to find the dimensions and the area of 2D shapes in order to find the surface area of 3D shapes. Finally, we filled an empty box with 2 centimeter blocks in order to find the volume of the shape.

## What is perimeter?

Perimeter = add all sides

## What is area?

Area of Rectangle = L*W

Area of Triangle = base x height / 2

Area of Parallelogram = base x height

## Suface Area

## What is suface area?

Surface Area of Pryamid = (LxW) + 4(BxH/2)

Surface Area of Rectangular Prism = 2(LxW) + 2(LxW) + 2(LxW)

## Volume

## What is volume?

Volume of Rectangular Prism = LxWxH
