Question

The mattress of a water bed is 4.00 m long by 4.00 m wide and 30.0 cm deep. calculate the weight of the water in the mattress.

Answer 1

If the density of the mattress is 1000 kg/m³. Then the mass of the mattress will be 4800 kg.

What is density?

Density is defined as the mass per unit volume. It is an important parameter in order to understand the fluid and its properties. Its unit is kg/m³.

The mass and density relation is given as

mass = density × volume

The mattress of a water bed is 4.00 m long by 4.00 m wide and 30.0 cm deep. And the density of the mattress is 1000 kg/m³.

Then the mass of the mattress will be

M = 1000 x 4 x 4 x 0.3

M = 4800 kg
