Question

Suppose that you purchased a water bed with the dimensions 2.55 m à 2.53 dm à 245 cm. what mass of water does this bed contain

Answer 1

dimensions of the bed is given as

`length = 2.55 m`

`thickness = 2.53 dm = 0.253 m`

`width = 245 cm = 2.45 m`

now the volume of the bed is given as

`V = 2.55 * 0.253 * 2.45 m^3`

`V = 1.581m^3`

now the mass of water in it is given as

`mass = density * volume`

`mass = 1000* 1.581`

`mass = 1581 kg`

so it will contain 1581 kg mass in it
