Answer:
The volume of a bar of gold with a mass of 66.5 grams is 
Step-by-step explanation:
Given , mass(in grams) ∝ Volume (in cm3)
Here, volume of 95 grams bar = 5cm3
So, thevolume of 1 gram bar =
= 
⇒The volume of a bar with weight 66.5 grams = 
So, the volume of a bar of gold with a mass of 66.5 grams is 
sqrt 7 ( sqrt 14 + sqrt 3 )
distribute
sqrt(7) sqrt(14) +sqrt(7) *sqrt(3)
sqrt(98) + sqrt(21)
sqrt(49*2) + sqrt(21)
sqrt(49) * sqrt(2) + sqrt(21)
7sqrt(2) + sqrt(21)
