Solution: অনুবাদঃ একটি আয়তাকার বাক্সের প্রস্থ 10 ইঞ্চি, দৈর্ঘ্য 10 ইঞ্চি এবং উচ্চতা 5 ইঞ্চি হলে ঐ বাক্সের দুটি বিন্দুর সম্ভাব্য বৃহত্তম দূরত্ব কত হতে পারে ? প্রশ্নটিতে What is the greatest possible (straight line) distance between any two points on the box বের করতে হবে । আর বাক্সের ক্ষেত্রে Greatest possible (straight points) distance between any two points আসলে Diagonal বা কর্ণের দৈর্ঘ্য । তাই আমরা আয়তাকার বাক্সের Diagonal বা কর্ণের দৈর্ঘ্য বের করবো । দেয়া আছে, দৈর্ঘ্য, Length = l = 10 inches প্রস্থ, Wide = b = 10 inches উচ্চতা, Height = h = 5 inches আমরা জানি, ঘনবস্তুর কর্ণের দৈর্ঘ্য, d = এক্ষেত্রে, Diagonal (distance) = = = 15Related questions
