Answer: mass = 485 grams approximately
=======================================================
Work Shown:
First we need the volume of the block
volume = (length)*(width)*(height)
volume = (4.22)*(3.62)*(1.41)
volume = 21.539724
volume = 21.5 cubic cm
I'm rounding to three sig figs because each of the dimensions are to three sig figs.
--------------------------
Now turn to the formula
density = mass/volume
This can be rearranged to
mass = density*volume
Plug in the given density and the volume we found earlier to get
mass = density*volume
mass = (22.57)*(21.5)
mass = 485.255
mass = 485 grams
I'm rounding to three sig figs because it's the smaller sig fig count of 22.57 and 21.5
