## Unit Description

## What was this unit about?

This unit we learned Perimeter Area of a square and rectangle Area of triangles Area of parallelogram and Surface of Area and Volume.

## What is Perimeter?

The distance around a two-dimensional shape. Perimeter is measured in units.

Perimeter: units

## What is area?

Area is the amount of space inside the boundary.

Area is measured in square units.

Area of Rectangle or Square = Length x Width

Area of Triangle = Base x Height / 2

Area of Parallelogram = Base x Height

## What is Surface Area?

Surface Area is a three-dimensional shape is a solid shape that has height and depth.

Surface Area is measured 2(LxW)+2(LxW)+2(LxW)

Surface Area of Rectangular Prism Length x Width x height

How to find the surface area of a rectangular prism

## What is Volume?

Volume is a space occupied by an object measured in three dimensions

Volume is measured = length x width x height

Volume of Rectangular Prism = length x width x height
