Question

How many kilograms of water can completely fill a

rectangularbox with dimensions 10.0cm by 5.0cm by 2.0cm?

Answer 1

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

`\rho = (m)/(V)`

Here,

m = mass

V = Volume

The volume of a rectangular box will be

`V = 10*5*2`

`V = 100cm^3 = 1*10^(-4)m^3`

Water density is given under normal conditions such as
`1000kg / m ^ 3`

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

`m = \rho V`

`m = (1000kg/m^3)(1*10^(-4)m^3)`

`m = 0.1Kg`

Therefore there are 0.1Kg of water.
