Estimating Concrete Blocks

[@donaldmusic6274]

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

[@jayleenebonaparte-primus6339]

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

Way better explanation that the video

[@joeteejoetee]

That was well simplified - thank you sir!

[@lisanaedwards4690]

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

[@jonathanmathau7401]

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

[@johnmccaffrey1336]

add three for under the mixer to raise it up

[@syedmohtashimali1044]

Good video love it

[@jonathanhoover6142]

Super helpful! Thank you sir

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

[@bmo5082]

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.

Easy enough for even me to understand.

[@mrhammerandnails1]

Awesome! Thank you for your positive feedback.

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

[@larrywolenskimechanical1951]

let me see if I can make this as simple as I can. I'm assuming you have two walls that are 40' and two walls that are 50'. Both walls are 20' high right?

[@63flight]

4,050

How much black hole in a 10x30 concrete wall

[@larrywolenskimechanical1951]

which is the height 10 or 30?

[@sarahconor8245]

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

[@mrhammerandnails1]

I really appreciate your comment. Thank you!

[@dutchesscarniegegordon56]

Thank you you are good at Math appreciate it

[@peterwayne6434]

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

[@mrhammerandnails1]

Multiply 6 x 60 a d a quarter of the width 6 by half of the length 60 and add both 6 x 60 = 360 1.5 x 30 = 45 405 (8"×8"×16". blocks are needed. Thank you for subscribing to my channel!

[@tiffanywilliams194]

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

[@larrywolenskimechanical1951]

what part don't you get?

[@losoway105]

Understand the formula , forget about the numbers and go step by step and repeat till you get it ! Practice makes you better

[@leothelion2001]

Calculate total area of the wall height 8' x length 20' = 160 Then divide the height 8÷4 =2 Then divide the length 20÷2 = 10 Multiply 2x10 plus 160 = 180

[@leothelion2001]

I just do it in decimals because regular calculator won't factor in inches though Therefore , area of the block is 16" x8" = 1.33x 0.67 = 0.8911 Finally divide the total area of the wall 160 ÷0.8911 = 180 you're welcome 😊

[@vishal.ontario]

Divide the area of the wall by area of one block...... wall 20 x 8 = 160 Square ft Block = 16" x 8" = 128 square inches = 0.889 Square ft (160/0.889 = 179.9775 or 180 Blocks, Simple!!!!

[@lisanaedwards4690]

Lol I see
