If a cube-shaped cell is 3 units tall by 3 units wide and 3 units long, what is the cell's surface-area-to volume ratio?
1 answer:
The cube has 6 sides, each a square with dimensions 3 by 3,
the area of any of these squares is 3*3=9 square units.
The total area of the cube is 6*9 square units=54 square units
The volume of a cube with side length a is given by :
, thus the volume of the cube-shaped cell is 3*3*3=27 cube units.
(surface area):(volume)=54:27 = 2:1 =2
Answer:
the ratio of the numerical values is 2
(their ratio including units is 2/unit

Answer:
Step-by-step explanation:
Isolate n on one side of the equation.
First, subtract 12 from both sides.
4n+12-12=4-12
Solve.
4-12=-8
4n=-8
Then, divide by 4 from both sides.
4n/4=-8/4
Solve.
Divide the numbers from left to right.
-8/4=-2
n=-2
So, the final answer is n=-2.
