Question

A cube with sides 12 cm is submerged in water to a depth of 30 cm. Given density of water is 1000 kg/m3. Calculate the pressure at the bottom surface of the cube due to water.​

Answer 1

Answer:

P=2940 Pa

Explanation:

Given that,

Side of a cube, a = 12 cm

It is submerged to  depth of 30 cm

The density of water, d = 1000 kg/m^3

We need to find the pressure at the bottom surface of the cube. We know that the pressure exerted is given by :

$P=d gh\\\\P=1000\ kg/m^3\times 9.8\ m/s^2\times 0.3\ m\\\\P=2940\ Pa$

So, 2940 Pa of pressure is exerted at the bottom surface of the cube due to water.​
