To solve this problem we will apply the concept related to density, which is defined as a scalar magnitude referred to the amount of mass in a given volume of a substance or a solid object. Mathematically it is expressed as

Here,
m = mass
V = Volume
The volume of a rectangular box will be


Water density is given under normal conditions such as

Therefore using the above formula and clearing for the dough we will have to



Therefore there are 0.1Kg of water.
