Answer :

To cover an area of 4.3m x 4.3m using blocks of 18 inches by 8 inches, we would need approximately 200 blocks.

To find out how many blocks are needed, we first convert the block dimensions from inches to meters:

  • 18 inches = 18 × 0.0254 = 0.4572 meters
  • 8 inches = 8 × 0.0254 = 0.2032 meters

Next, calculate the area of one block:

Area of one block = 0.4572 m × 0.2032 m = 0.09284384 m²

Now, the given area to be covered is:

4.3 m × 4.3 m = 18.49 m²

To find the number of blocks required, divide the total area by the area of one block:

Number of blocks = 18.49 m² / 0.09284384 m² ≈ 199.16

Since we can't have a fraction of a block, we'll need 200 blocks to completely cover the area.
