A cube edge increases at 5 cm/s. How fast does its volume increase when its edge is 15 cm?
✅ Step-by-Step Solution
Final Answer: 3375 cm³/s
- For edge a, V=a³ gives V̇=3a²ȧ=3(15)²·5=3375.
- 3375 cm³/s
📋 CBSE Stepwise Marking Scheme
- [0.5 marks] For edge a, V=a³ gives V̇=3a²ȧ=3(15)²·5=3375.
- [0.5 marks] 3375 cm³/s
