আমরা জানি, 1 গজ = 3 ফুট সুতরাং, 1 বর্গ গজ = 1 গজ × 1 গজ = 3 ফুট × 3 ফুট = 9 বর্গফুট এখন, বর্গাকার স্থানটির ক্ষেত্রফল হল 4 বর্গ গজ। 4 বর্গ গজ = 4 × 9 বর্গফুট = 36 বর্গফুট প্রতিটি পাথরের ক্ষেত্রফল হল 4 বর্গফুট। প্রয়োজনীয় পাথরের সংখ্যা = (মোট ক্ষেত্রফল) / (প্রতিটি পাথরের ক্ষেত্রফল) প্রয়োজনীয় পাথরের সংখ্যা = 36 বর্গফুট/4 বর্গফুট = 9 সুতরাং, 4 বর্গ গজ বর্গাকার স্থানকে আচ্ছাদন করতে 9টি 4 বর্গফুট আয়তনের পাথরের প্রয়োজন হবে।Related questions
