well what is 10% of 100 meters? if you know that, take that from 100 meters and then use the result to calculate the volume :) you have all the other values needed ;)

original height = 100
removed height = 10% x 100
the new height = original height - removed height

now you have the new height, you have the width, you have the length.
volume = height * width * length
put in the values and tell me what you get :)
