There are 144 square inches to the sq. foot....at 120 blades of grass per sq. inch it would have 17,280 blades to every sq. foot. 17,280 blades times 160 square feet of surface to the lawn would equal 2,764,800 blades of grass.

How many blades of grass on a football field?

First you would have to determine how many were in a smaller area like 1 square foot. This you would have to actually count. Then you would have to figure how many square feet there were to a football field. 150' X 300' equals 45,000 square feet. Multiply the number of blades of grass that you counted in one square foot, times 45,000 and that would tell you approximately how many blades there were. This would be a guess. Or if the field is astroturf then it's easy. Zero. Well there's about 10 blades of grass on a square inch keeping in mind that there's about 39 inches in a meter u do 39x39=15210 per square meter a football field measures about 110 m x 49m... if u take 110x 49= 5390m is the area of a football field u take 5390(area of the football field in meters)x15210(the amount of grass blades in a square meter u get 81,981,900 grass blades on a football field in other words.. 5390x15210= 81, 981,900 blades of grass on a football field per square meter....i only did this because my physics teacher asked us this question n i was online looking for the answer n i found none that were useful n i decided since i found the answer half an hour later to post the answer n the method i used....hope this helps


A pound of grass seed covers 4000 square feet of lawn Then how many pounds of grass seed are needed to cover a lawn measuring 150 feet by 160 feet?

150 ft * 160 ft = 24 000 square feet. 4 000 sq feet of lawn requires one pound of seeds so 24 000 sq ft of lawn will require 6 pounds of seed.


Should the 3 numbers on fertilizer equal 100?

No. The first number helps you figure out how much to spread over a thousand square feet of grass to add up to the one pound of "actual nitrogen" that one thousand square feet of grass needs. Example: You have a bag of 29-6-4. Divide 100 by 29 and you get about 3.5. This means you need to spread 3.5 pounds of this stuff for your grass to get the one pound of "actual nitrogen your grass wants during the growing season.


Judy has a rectangular garden 14 by 19 feet She wants to put a grass border around the garden with a uniform width on all sides If she has enough grass seed to cover 430 square feet how wide can the g?

Imagine the uniform width be "x" now the total area (area of the garden + area of border) - (area of the garden) = 430 so ((14+x)(19+x)) - (14*19) = 430 x = 10 so the width will be 10 feet uniform around the garden


What is the perimeter of an area 12 feet by 10 feet?

Sure thing, darling. The perimeter of a rectangle is calculated by adding up all the sides, so for a 12 feet by 10 feet area, you just add 12 + 12 + 10 + 10, which gives you a grand total of 44 feet. Voila, you've got your perimeter!
