Download Solution PDFदिलेल्याप्रमाणे:
एका लम्ब पिरॅमिडचे एकूण पृष्ठफळ 208 सेमी2 आहे, ज्याचा पाया 8 सेमी बाजूचा चौरस आहे.
वापरलेले सूत्र:
एकूण पृष्ठफळ = बाजूकडील पृष्ठफळ + पायाचे क्षेत्रफळ
बाजूकडील पृष्ठफळ = 1/2 × पायाची परिमिती × तिरकी उंची
गणना:
प्रश्नानुसार,
208 = बाजूकडील पृष्ठफळ + 82
⇒ 208 - 64 = बाजूकडील पृष्ठफळ
⇒ 144 = बाजूकडील पृष्ठफळ
पुन्हा,
144 = 1/2 × 4 × 8 × तिरकी उंची
⇒ 144/16 = तिरकी उंची
⇒ 9 = तिरकी उंची
∴ पिरॅमिडची तिरकी उंची (सेमी मध्ये) 9 आहे.
