Question

anonymous · Answer

that's the question

anonymous · Answer

23/8 is the time she exercises, and she is running 2/7 of that time.  This should tell you how much she runs every Saturday.  The key is "of the time," and you know the time.

mertsj · Answer

Do you know that, in mathematics, "of" means "times"?

I don't know please help me

mertsj · Answer

As I posted a moment ago:
Volume = length times width times height.

mertsj · Answer

What is the length of the room?

anonymous · Answer

it only says 8 feet long and 8 feet wide with 7-foot ceilings

mertsj · Answer

So how long is the room?

anonymous · Answer

8 feet long :)

mertsj · Answer

So if the room is 8 feet long that means that its length is 8.
How wide is the room?

anonymous · Answer

8 feet wide

mertsj · Answer

So if the room is 8 feet wide that means that its width is 8.
How tall is the room?

anonymous · Answer

7-foot ceilings

mertsj · Answer

If the ceiling is a 7 foot ceiling that means that the room is 7 feet high and that means that the height is 7 feet.
Now can you find the volume?

anonymous · Answer

noo I don't understand soo u have to add 8+8and then whatthe answer of 8+8 you have to multiply by 7 ???

mertsj · Answer

Volume = length x width x height

mertsj · Answer

Do you know what length x width means?
