To calculate the amount of concrete needed for a 30'x40' slab, you first need to determine the thickness of the slab. For example, if the slab is 4 inches thick, convert the dimensions to feet (30' x 40' x 0.33' for 4 inches). Then, multiply the length, width, and thickness: 30 x 40 x 0.33 = 396 cubic feet. To convert cubic feet to cubic yards, divide by 27, resulting in approximately 14.67 cubic yards of concrete needed.

It costs Rs.12 Lakhs for a very normal house. For a good & attractive house costs 17 lakhs depending on your requirement & taste for 30x40 or 12 squares.
30x40=? Let's find out. What's 3x4? 12. Ok. So the 3 and 4 are out of the problem now. Look back at the problem. We see two zeros. We already took care of the 3 and 4. So what do we do with the zeros? You add them on to the number you already have. So 4x3=12. So it is 1,200. 30x40=1,200.
1200 sq.ft. 30x40=1200
To determine how many 30x40 bond papers are equal to one ton, we need to know the weight of a single sheet. Typically, 30x40 bond paper weighs around 100 pounds per ream (500 sheets). Therefore, one sheet weighs about 0.2 pounds. To find out how many sheets equal one ton (2,000 pounds), you would divide 2,000 by 0.2, resulting in 10,000 sheets of 30x40 bond paper per ton.
