No. You cannot convert cubic meters in length, width, and height without any further information.
Without further information it is not possible to answer the question.
You can't if you don't what the height and width is.
This question cannot be answered sensibly. A metre square is a measure of area, with dimensions [L2]. A height is a linear measure, with dimensions [L]. Basic dimensional analysis teaches that you cannot convert between measures with different dimensions such as these without additional information.
You do not convert height to metres, you MEASURE height in metres (or centimetres, or feet or miles).
You can't convert length to volume without knowing the width and height. I assume you mean millimeters. If so, you multiply a metre by 1000 to get millimeters.
Without knowing your height, it would be impossible to tell. If you are, say, 5' 8" to 5' 11", you are not obese. If you happen to be 5' 2", then you might have a problem. ---- For further information, please see the related page link, further down this page, listed under "Related Questions."
Weight is worked out on height not age. For further information about weight in relation to height, see the page link, further down this page, listed under "Related Questions."
You cannot without a lot more information about the shape.

The volume of a cone is given by the formula V =⅓πr2h where r is the radius of the base and h is the vertical height. If the volume is known there are still two unknowns, r and h and therefore the problem cannot be solved without at least one further piece of relevant information.
