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!

[@fish9529]

Thank you so much for the positive feedback. May God bless you too and may the exams go well!

[@minhajnaqvi7611]

Your videos are getting me hooked with surveying .......Respect.

[@fish9529]

Thanks, all of the best with the studies!

Mr.Fish is a certified LEGEND!

[@fish9529]

Certified nogal! I enjoyed that one 😉

[@alhajiyussuf2467]

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

[@fish9529]

Thanks for the feedback. I'm planning to make more videos, so I'll keep it in mind. All of the best with the studies!

[@lolplays1102]

You are very helpful. Thank you so much sir.☺

[@fish9529]

You're welcome, all of the best with the studies!

[@OSAS726]

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

Thank you. You really helped out. :)

This man is a hero

[@fish9529]

A teacher isn't called a hero often lol! Thanks for watching anyway and may the studies go well.

Thanks sir I get it clear and we'll understood

[@fish9529]

Glad to hear that!

You did amazing sir

This was helpful

Can you explain strip method on the map it will be helpful for me

[@gugulethujamjam8444]

Sorry what happens if you are given the area of the irregular shape and asked to calculate the number of squares equaling 1 hectare?

[@fish9529]

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.

[@vanillla8216]

Where have you been all life

[@metal422life]

"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

[@syakirahmohamad6465]

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?

[@fish9529]

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: kzbin.info/www/bejne/oZrKamiuqt-Yq8U

[@syakirahmohamad6465]

@@fish9529 its okay... thank you sir for your clear explaination...

What a legend 💪🏼🔥

[@ggkphilosophy]

Hi can anyone help me using this technique i wish to calculate the size of some parts of the mediteranens. Using paint

[@Catubrannos]

The paint will float away, you should use a map instead.

[@killuazoldycke]

Can't you do it with integrals?

May it go well!

[@samuelntouba4879]

how to calculate map

[@tsegahchristopher7532]

please i do not understand how you were able to get the final answer. how did you get the final answer.

[@fish9529]

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.

[@oriettasithole485]

How Area of land is calculated when given scale bar of 3.0km,Not 1:50 000

[@grizzkid795]

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.

[@harithizaham5819]

Why 1/2 divide by 2?

[@fish9529]

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.

[@tsegahchristopher7532]

hey sir I will like you to send me this video through sky walker that is my facebook name please

[@fish9529]

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: kzbin.info/www/bejne/javHgJmHd8pnirc.

[@grizzkid795]

Interesting, this is not an exact calculation, as he ssys, "more or less".
