Question

A rectangular swimming pool has the dimensions of 26m long, 4m wide, and 2.5 m deep (high). The density of the water in the pool is 1.62 g/m3. What is the mass of the water in the pool? (hint: volume of a rectangle is L x w x h) Show your work!

Answer 1

`m=421.2g`

Step-by-step explanation:

Hello.

In this case, we first compute the volume of the pool via:

`V=L*W*H\\\\V=26m*4m*2.5m\\\\V=260m^3`

Then, since the density is defined as the mass divided by the volume, we compute the mass as follows:

`\rho=(m)/(V)\\ \\m=\rho*V\\\\m=1.62g/m^3*260m^3\\\\m=421.2g`

Best regards.
