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
