The inside of a rectangular carton is 48 centimeters long, 32 centimeters wide, and 15 centimeters high. The carton is filled to capacity with k identical cylindrical cans of fruit that stand upright in rows and columns, as indicated in the figure above. If the cans are 15 centimeters high, what is the value of k ? (1) Each of the cans has a radius of 4 centimeters. (2) Six of the cans fit exactly along the length of the carton.
可我没有看出哪里提到cylinder的高度刚好放在rectangular的15cm的方向啊? 有个图我没法放上来。谢谢 |
