0.004 m3 = how many cubic millimeters

0.004 m3 = how many cubic millimeters

0.004 m3 = 4 000 M3

How many tons does a cubic meter of sand weigh?

The composition of sand varies from place to place, so the weight of sand varies
Generally, it is assumed that the specific gravity of sand is 1.8 × 1000 kg / m3, so one cubic meter of sand weighs about 1.8 tons

How to measure the sand on the car?

Generally, the sand in the upper part can't be a standard cone with a square bottom, but in fact, it is a cone close to the round bottom, which can be calculated approximately by half of the volume sum of the two cones
(the volume of the cone with the length of the car as the diameter of the round bottom + the volume of the cone with the width of the car as the diameter of the round bottom) / 2
Is the approximate volume of the roof cone
If you need to know the actual volume, you have to weigh it and divide it by density. This is very standard
