एक छोटा पौधा घर (green house) सम्पूर्ण रूप से शीशे की पट्टियों से (आधार भी सम्मिलित है) घर के अंदर ही बनाया गया है और शीशे की पट्टियों को टेप द्वारा चिपका कर रोका गया है। यह पौधा घर 30 cm लंबा, 25 cm चौड़ा और 25 cm ऊँचा है।(i) इसमें प्रयुक्त शीशे की पट्टियों का क्षेत्रफल क्या है?(ii) सभी 12 किनारों के लिए कितने टेप की आवश्यकता है? |
|
Answer» Answer: शीशे की पट्टियों का क्षेत्रफल 4250 cm² है।सभी 12 किनारों के लिए 320 cm टेप की आवश्यकता है।Step-by-step EXPLANATION: दिया है : पौधे घर की विमाएं ,लम्बाई (L) = 30 cm, चौड़ाई (b) = 25 cm और ऊँचाई (h) 25 cm
(i) शीशे की पट्टियों का क्षेत्रफल = 2(lb + bh + lh) = 2(30 ×25 + 25 ×25 + 25× 30) = 2(750 + 625 + 750) = 2 × 2125 = 4250 cm² अतः , शीशे की पट्टियों का क्षेत्रफल 4250 cm² है।
(ii) टेप की लंबाई = 4(l + b + h) = 4(30 + 25 + 25) = 4× 80 टेप की लंबाई = 320 cm अतः ,सभी 12 किनारों के लिए 320 cm टेप की आवश्यकता है।आशा है कि यह उत्तर आपकी मदद करेगा।
इस पाठ से संबंधित कुछ और प्रश्न : एक घनाकार डिब्बे का एक किनारा 10 cm लंबाई का है तथा एक अन्य घनाभाकार डिब्बे की लम्बाई, चौड़ाई और ऊँचाई क्रमशः 12.5 cm, 10 cm और 8 cm हैं। (i) किस डिब्बे का पार्श्व पृष्ठीय क्षेत्रफल अधिक है और कितना अधिक है? (ii) किस डिब्बे का कुल पृष्ठीय क्षेत्रफल कम है और कितना कम है? किसी आयताकार हॉल के फर्श का परिमाप 250 m है। यदि 10 प्रति [संकेत : चारों डिब्बों का क्षेत्रफल = पाश्र्व पृष्ठीय क्षेत्रफल ] |
