Question

anonymous · Answer

find the volume of a ball with radius 2cm , find the volume of the room , and divide the volume of the room with the volume of the ball and u see how much balls will fit in the room

anonymous · Answer

Find the volume of the ping pong balls and find the volume of the room.

than do this 

Volume of room/ volume of ping pong balls = total number of ping pong balls that fit in the room!!

Recall that the volume of a ping pong ball is $$V = \frac{ 4 }{ 3 } \pi r ^{3}$$

anonymous · Answer

Is the final answer 40.9426?

anonymous · Answer

yeah its right

anonymous · Answer

just round it to 40 because you don't want them to break in the room lol..haha right..=))

anonymous · Answer

But, aren't we supposed to convert 1372 ft^3 (which is the volume of the room) into cm^3? And then divide that by the volume of the balls?

anonymous · Answer

yes good that's right good pick up!

Also, doesn't make any logic that just 40 ping pong balls fit in a room 14 x 14 x 7.
