To find the square footage of a room, you multiply the length by the width. For a room that is 20 feet by 50 feet, the calculation would be 20 x 50 = 1,000 square feet. Therefore, the square footage of the room is 1,000 square feet.
To calculate the number of hollow blocks needed for a 70,000 square meter wall at a height of 7 feet, first convert the height to meters (7 feet ≈ 2.13 meters). The total wall area would be 70,000 m² × 2.13 m = 149,100 m². Assuming an average hollow block size of 0.4 m², you would need approximately 372,750 blocks (149,100 m² ÷ 0.4 m²). Adjust for waste and mortar gaps as necessary.

Assuming they are 8 inch*16 inch blocks, 144 square feet = 144*12*12 square inches. So number of blocks required = 144*12*12/(8*16) = 162
How many square shingles
Ah, what a happy little question! When you have a rectangle that's 20 feet long and 50 feet wide, you can find the square footage by multiplying those two numbers together. So, 20 multiplied by 50 equals 1000 square feet of space to fill with all sorts of wonderful creations. Just imagine all the beautiful landscapes you could paint in that much room!
There are 30 square feet in a room that measures 6 feet by 7 feet. Visualize this: There are 6 columns of 7 blocks, and 7 rows of 6 blocks. You add all of the blocks up to get 30, or you can just mutiply 6 by 7.

370 8 x 8 concrete blocks equal approximately 164 square feet.

Most ordinary residential blocks are 330 feet by 660 feet (measured centerline of street to centerline of street). Downtown blocks are sometimes smaller, and some outlying blocks are larger.
Real-estate covered by each block = length x width = 2 x 3 = 6 square feetNumber of blocks required = 672/6 = 112
I think perhaps 2250 blocks .
If the blocks are 12 inches x 12 inches then each block measures 1 square foot. An area of 14 feet x 14 feet has a surface area of 196 square feet, so it would require 196 of the 12" x 12" blocks to cover it.
