Let’s check out your problem:

A copper cube that is 
15cm on each side is suspended from a spring scale and then placed in water? How much will the cube "weigh" in the water? The density of copper is 
8,940(kg)/(cm^(3)).
Our bodies displace the fluid air that we live in. Therefore, the air live in exerts a buoyant force on our bodies. Determine the magnitude of the buoyant force on a 
80kg person due to

Q. 33. A copper cube that is 15 cm 15 \mathrm{~cm} on each side is suspended from a spring scale and then placed in water? How much will the cube
  1. Calculate Volume: Calculate the volume of the copper cube. Volume = side length3^3 = 15cm×15cm×15cm=3375cm315 \, \text{cm} \times 15 \, \text{cm} \times 15 \, \text{cm} = 3375 \, \text{cm}^3.
  2. Calculate Mass: Calculate the mass of the copper cube using its density.\newlineMass = density ×\times volume = 8,9408,940 kg/cm3^3 ×\times 3,3753,375 cm3^3 = 30,165,00030,165,000 kg.
