Answer:
3 grams per cubic centimeter.
Explanation:
density = mass ÷ volume.
d = m ÷ v.
m=81 g.
volume = length × width × height.
volume = 3 cm × 3 cm × 3 cm = 27 cubic centimeters.
v = 27 cubic centimeters.
d = 81 ÷ 27
density = 3 grams per cubic centimeter.
The correct answer is Account B (the second option)
