\/
W + 3 + W + 3 + W + W= 84
\/
4W + 6 = 84
\/
4W = 78

W = 19.5 L = 19.5 + 3 = 22.5
I hope this helps, have a nice day! :D
1.0g/cm3 means that the mass of one cm3 is 1.0g
The easiest method to use is the rule of three, and let x be the mass of 10.0 cm3 of water
1g -- > 1.0 cm3
x --> 10.0 cm3
x= (10*1)/1
x=10.0 g
So the mass of 10.0 cm3 of water is 10.0g
Hope this Helps! :)
