Question: How Many Squares are there on a Chess Board?
- 64
- 204
- 128
- 400
Answer: (B) 204
How Many Squares are there in a Chess Board? Solution: A standard chessboard consists of 8 rows and 8 columns, each containing 8 squares. Therefore, the total number of squares on the board is 8 x 8 = 64. However, there are also smaller squares that can be formed by combining adjacent squares. For instance, there are 49 squares formed by combining 2×2 squares, 36 squares formed by combining 3×3 squares, and so on.
To determine the total number of squares, we can systematically count the squares of each possible size, starting from the smallest:
- 64 1×1 squares
- 49 2×2 squares
- 36 3×3 squares
- 25 4×4 squares
- 16 5×5 squares
- 9 6×6 squares
- 4 7×7 squares
- 1 8×8 square
Adding up the squares of all sizes, we arrive at the total number of squares on a chessboard:
64 + 49 + 36 + 25 + 16 + 9 + 4 + 1 = 204 squares
How Many Squares are there in a Chess Board?
- There are a total of 204 squares on a standard chessboard.
Is It Important to Increase the Area Under Irrigation Why?
Increasing the area under irrigation is crucial for several reasons. It enhances agricultural productivity, ensuring food security for growing populations. Irrigation helps mitigate the impact of erratic rainfall and droughts, providing a consistent water supply for crops. Moreover, expanding irrigated areas can lead to improved crop diversification, allowing farmers to grow a variety of crops year-round. This diversification supports rural economies and livelihoods. Additionally, better irrigation practices contribute to efficient water management, reducing wastage, and promoting sustainable agricultural practices. Overall, increasing the area under irrigation is vital for sustainable development, economic stability, and environmental conservation.
