Homework Statement
A weight is 20 centimeters in length, 20 centimetres in width, 5 centimetres in height. Its mass is 1.5 kg. Find the weight's weight in water.
m = 1.8 kg
h = 5 centimeters = 0.05m
l = 20 centimeters = 0.2 m
width = length
Homework Equations
FA = pliquidgV
P = mg
The Attempt at a Solution
There is a drawing in the attachment. I know i should of put measurements there.
Now my problem. Should i attempt to put the weight in equilibrium so i could:
FA - P = 0
FA = P
FA = mg
pliquidgV = mg
pliquidghlw = mg
And then what?
