Estimating Concrete Blocks

When I had math class they explained why. Not just how to get a result using a "formula"

wow, thank you, you made it so simple. Please do more

Good video love it

Would this work for any scenario ? Like a 3 sided and smaller project

Super helpful! Thank you sir

That was well simplified - thank you sir!

Can you give me a estimate for 16×8×8 block .measurements is 6×60

how many cinder blocks to make a 40 by 50 building 20 feet high with 8 by 8 by 16' blocks ?

How much black hole in a 10x30 concrete wall

Great video. I always laugh when people say you dont need to know this type of math to function in the real world. Well, try bidding out any construction job or do any construction job without being able to do the math.

The way i estimate the amount of blocks needed, is i take the face area of the block, and divide that into the total face area. The face are of a block is .888889 SF and your project is 8x20 or 160sf. So, 160sf / .8888889 = 180 blocks.

A block is 7.5 inches tall plus 1/2 inch for mortar = 8 inches tall. usually 4 to 8 inches wide and the length is 16 inches. these sizes is including the 1/2 inch mortar. to calculate a 20 feet long wall will be 20 feet x 12 inches (converting the feet to inches for better calculation)= 240 inches then divide by the 16 inch of the block which will be 15 blocks on the floor. to calculate how many block going up. each block is 8 inches tall therefore you multiply the height of the wall white is 8 feet x 12 inches = 96 inches tall. then divide by the height of a block ( 8 inches) you will get 12 blocks. then you multiply the 12 x 15 = 180 blocks
and thats the total blocks needed

Thanks. You are a great teacher. Concepts made simple=people learning

Thank you you are good at Math appreciate it

I still don't get it. I hate being terrible at math!

Lol I see

How do you get 180 I'm lost at that point

Thank u for sharing. U made it look so simple tho

Easy enough for even me to understand.
