This question cannot be answered sensibly. A cubic metre is a measure of volume, with dimensions [L3]. A kilogram is a measure of mass, with dimensions [M]. Basic dimensional analysis teaches that you cannot convert between measures with different dimensions such as these without additional information. It takes only a little mental effort to compare a cubic metre of air and a cubic metre of lead and come to the conclusion that the two will have very different masses.
Assuming the measurments in the question are in inches. 72 × 13.5 × 3 = 2916 cubic inches
1150 + 1766 = 2916
It could be almost anything unless you tell us at least one of the other measurements.
29.16 = 2916/100 = 729/2529.16 = 2916/100 = 729/2529.16 = 2916/100 = 729/2529.16 = 2916/100 = 729/25
The square root of 2916 is 54.

It is: 54*54 = 2916
In today's notation of Roman numerals 2916 = MMCMXVI
