Answer (Detailed Solution Below)
Detailed Solution
Download Solution PDFचौरसाची बाजू = 7 सेमी
पत्र्यामधून कापलेल्या प्रत्येक लहान चौरसाचे क्षेत्रफळ = 0.25
पत्र्यामधून कापलेल्या प्रत्येक लहान चौरसाची बाजू = √0.25 = √(0.5 × 0.5) = 0.5 सेमी
जर उरलेला पत्रा कापलेल्या बाजूने दुमडला तर घन तयार होईल
घनाची लांबी = 6 सेमी
घनाची रुंदी = 6 सेमी
घनाची उंची = 0.5 सेमी
आपल्याला माहीत आहे की, घनाचे घनफळ = लांबी × रुंदी × उंची
घनाचे घनफळ = 6 × 6 × 0.5 = 18 सेमी3
