A hollow sphere is melted to form small identical hollow spheres. Inner and outer radius of the bigger sphere are 4 cm and 6 cm respectively. If inner and outer radius of the smaller sphere are 2cm and 3 cm respectively, then how many smaller spheres can be formed? एक खाली गोले को पिघलाकर समान खाली छोटे गोले बनाए गए हैं। बड़े गोले की आंतरिक तथा बाह्य त्रिज्या क्रमशः 4सेमी तथा 6सेमी है। यदि छोटे गोले की आंतरिक तथा बाह्य त्रिज्या क्रमशः 2 सेमी तथा 3 सेमी है, तो कितने छोटे गोले बन सकते हें?
