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 ;)

ok so let's do this step by step :) 10% of 100 = $$\large \frac{10}{100} * 100 = ?$$ what's the answer?

original height = 100 removed height = 10% x 100 the new height = original height - removed height |dw:1345839694695:dw|

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 :)
