## Material Cost

To calculate the cost of materials for a project, multiply the unit price by the amount needed. For example, you are adding grass to your backyard. Grass costs \$2 per square foot. Your yard is 30 feet long, and 40 feet wide. To calculate the total cost of grass, do the following:
```grass  = \$2/sqft
length = 30 feet
width  = 40 feet
area   = 30 feet × 40 feet = 1,200 sqft
cost   = \$2/sqft × 1,200 sqft = \$2,400
```
You are also building a fence around your yard. The wood for the fence costs \$15 per linear foot. You don't need a fence for one of the width sides of your yard, since that side is next to your house. To calculate the total cost of the fence, do the following:
```fence  = \$15/foot
length = 30 feet
width  = 40 feet
border = (30 feet × 2) + 40 feet = 100 feet
cost   = \$15/foot × 100 sqft = \$1,500
```
