There is insufficient information available to answer the question. If one dimension is increased, another can be decreased to compensate.
You need the density of your material, say you had a cubic metre of water which has a density of 1000 kilograms / cubic metre, then it would be 1000 * 1 = 1000 kg If it was 1 cubic metre of steel, density 7850 kg / cu m, then it would be 7850 * 1 = 7850 kg
steel density = 7850 kg per cubic metre volume = 0.6 * 1.2 * 0.003 = 0.00216 cu m mass = volume * density = 0.00216 * 7850 = 16.956 kg ( 37.3816 pounds )
This question cannot be answered sensibly. A cu ft is a measure of volume, with dimensions [L3]. A pound 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. As a simple mental exercise consider a cu ft of air and a cu ft of water. They will have very different weights.
If the dimensions given are inches, there are 49.11 cu. ft. If they are in feet there are 84,864 cu. ft.
weight = density * volumeUsing steel density @ 7850 kg / cu. metreDimensions in metres>volume = pi * r * r * l = 3.1416 * 0.0125 * 0.0125 * 1.0= 0.00049087 cu.metres>weight = 7850 * 0.00049087 = 3.853 kg
The box has a volume of 5400 cu. cm ( 329.5282 cu. inches ).
C; 56 cubic inchesthe cube is 6*6*6 =216 cu in The box is 4*4*10=160 cu in the difference is 56 cu in
Assuming the dimensions given are in feet, multiply length x width x depth to find the volume (cu ft) of the pool and multiply by the number of gallons of water per cu ft (7.481). V = 40 x 20 x 5 = 4000 cu ft x 7.481 = 29924 gallons
This question cannot be answered sensibly. A cubic metre is a measure of volume, with dimensions [L3]. A ton 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. A simple mental exercise will demonstrate that a cu metre of air and of lead will have very different masses.
