Question

A cubic meter of water weighs 1000 kg. What is the weights of 2 meters by 3 meters by 20 millimetre of water?

Answer 1

To find the weight of the water, we need to find the volume of the water first.

The volume of the water is given by the formula:
Volume = Length x Width x Height

Given:
Length = 2 meters
Width = 3 meters
Height = 20 millimeters

But the height is given in millimeters, so we need to convert it to meters:
Height = 20 millimeters = 0.02 meters

So the volume of the water is:
Volume = 2 meters x 3 meters x 0.02 meters
Volume = 0.12 cubic meters

Since a cubic meter of water weighs 1000 kg, the weight of 0.12 cubic meters of water is:
Weight = 0.12 cubic meters x 1000 kg/cubic meter
Weight = 120 kg

Therefore, the weight of 2 meters by 3 meters by 20 millimeters of water is 120 kg.
