एक ठोस गोले की त्रिज्या (R) 42 सेमी है।
इसे पिघलाकर समरूप छोटे ठोस गोले बनाए जाते हैं जिनकी त्रिज्या (r) 7 सेमी है।
प्रयुक्त सूत्र:
गोले का आयतन = \(\frac{4}{3}\times\pi\times r^3\)
गणना:
माना कि बनने वाले गोलों की संख्या x है।
⇒ गोले का आयतन = \(\frac{4}{3}\times\pi\times R^3=\frac{4}{3}\times\pi\times 42^3\)
इसे छोटे गोले में पिघलाया जाता है।
गोले का आयतन = छोटे गोलों का आयतन
⇒ \(\frac{4}{3}\times\pi\times 42^3=x\times\frac{4}{3}\times\pi\times 7^3\)
⇒ x = 6 x 6 x 6 = 216
अतः, बनने वाले छोटे ठोस गोलों की संख्या 216 है।
