घनाभ का कुल पृष्ठफल = 2lb + 2bh + 2hl या 2(lb + bh + hl)
यहां l, b और h लंबाई, चौड़ाई और ऊंचाई हैं।
घन का आयतन = a3
गणणा:
a3 = 729
⇒ a = 9 सेमी
घनाभ की लंबाई = 9 + 9 = 18 सेमी
चौड़ाई = 9 सेमी
ऊंचाई = 9 सेमी
घनाभ का कुल पृष्ठफल = 2 (18 × 9 + 9 × 9 + 9 × 18) = 810 सेमी2
∴ घनाभ का कुल पृष्ठफल 810 सेमी2 हैl
