Thank you so much for all the effort you've put into these videos. Doing last min revision before my exams tmmrw and I'm so grateful for your amazing videos. God bless you!
I really appreciate, you are audible and clear in your explanation. It really helped me a lot, I humbly request from you to produce more videos specifically on climate, thank you
Thank you so much for all the effort you put into making these videos. They are very informative. I was wondering if I just made the squares even smaller would that increase the accuracy of the area? or could you keep all the squares that are in whole areas larger and then in partial areas you could divide the regular squares up almost to an infinite amount of squares in order to fit them nice and neatly into the irregular shape and then make your calculation there? Your thoughts? I was even thinking about building a mechanical integrator to run my calculations. My third theory would be to try to find a calculus formula to solve for the area within the irregular shape. I know you can take functions on a Cartesian coordinate graph and integrate them by finding the anti-derivative and then evaluating between two points on the X axis. I know there’s a way to do it with calculus, but I haven’t made it that far in my calculus journey yet.. lol
"The teacher might say that it's in between this and this square kilometers". This is the teacher saying I honestly have no clue what the exact answer is and please don't ask me to find the exactly precise answer go pay a survey crew if you want the answer
Hi, good question. There are 100 hectares in 1 square km. So you'd first have to count all the hectares and then work it out. Use this link: www.asknumbers.com/hectare-to-square-kilometer.aspx I hope this helps.
Hello sir , i want to ask some question ....if my lecturer not give grid just scale n topography map with 1cm:0.5 km ...for draw the grid need use 2cm or 1cm?
Hi, sorry for the late reply. I would use 2 cm when I draw my grid. I have posted a video on scale conversion if you'd like to watch it. Here's the link: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-kig95xuzeuc.html
Hi again, you basically count all the squares. If your total amount of squares is 15, then the answer is 15 km². Just remember that if you have 8 half squares, you must divide by two, so your answer would be a total of 4 half squares. So, in the video, I first counted the full squares = 30. Then the half squares: 10 divided by 2 = 5. And the the 3/4 squares (these are counted as full squares as explained in the video: 5. So, then you add them all up: 30 + 5 + 5 = 40, so the answer is 40 km². I hope this helps.
Then you would have to figure out how many centimeters on the map equal a kilometer. For example, let's say two centimeters equal a kilometer.Then you devide two centimeters into a kilometer, which equals 50000, so thst would be 1:50000 scale.
Hi, if I understand your question correctly, you want to know why we say 10 divided by 2 when dealing with the half squares. This is because we don't want to count the half squares as full squares and that's why we divide by two. In other words, 10 half squares = 5 full squares. I hope this helps.
Hi again, I'm not that active on facebook. Can't you simply copy the link for this video and post it in facebook? Here's the link: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-WzdOfQBe4TU.html.
