قياس مساحة الكتاب
عند قياس مساحة الكتاب نضرب طوله في عرضه في ارتفاعه صح أو خطأ
الإجابة هي: خطأ، وذلك لأنه عند إيجاد مساحة شي ما، اضرب الطول في العرض.
قياس مساحة الكتاب بسيط للغاية. كل ما عليك فعله هو ضرب طوله في عرضه. سيعطيك هذا مساحة سطح الكتاب. على سبيل المثال، إذا كان طول الكتاب 5 سم وعرضه 4 سم، فإن المساحة 20 سم 2. يمكنك أيضًا قياس حجم الصندوق بضرب طوله وعرضه وارتفاعه. سيعطيك هذا الحجم ثلاثي الأبعاد للمربع. على سبيل المثال، إذا كان طول كل صندوق وعرضه وارتفاعه 5 سم، فإن الحجم يكون 125 سم 3.
