Formula for the surface area of a cube?

Question

I need to know if this statement is correct: the formula for the surface area of a cube with volume s^3 is 4s???

Answer 1

not quite it's 6s^2
6 for the 6 faces of a cube
s^2 for the surface area of each individual side

Given:
S^3 is the volume
S is the length of 1 side

Answer 2

A cube has 6 sides, and the area of a square is S^2 so the surface area = 6S^2.

You also have S^3=4s

Answer 3

Okay,
It's a cube. Lenght * height*width=volume in cubic measure.
Your volume is s^3, which is something new to geometry to me, so I'll attack, conquer and divide this like the neanderthal I am and let you make your own conversions.

If the cubic volume is 64, and all sides are equilateral, then the functional number is 4 for all multipliers. L=4, H=4 and W=4, (4*4=16 16*4=64.) So for surface area of the cube, take the facial area of one side, at 16 and multiply by 6. (Doing it in my head, 6*6 is 36 and 6*10 is 60, for a total surface area of 96 sq units.)

Good Luck

Answer 4

If you differentiate the volume of a cube, you get the surface area.

Answer 5

First, determine the area of a square. How many squares make up a cube? It'll be more than 4s.

Answer 6

well i substituted s as 4, so s^3 = 64 (4x4x4) and 4s (4x4) = 16 so i guess its wrong. the formula thing, is the width x length x number of faces. i think...

Answer 7

For any rectangular prism, SA is 2WH + 2WD + 2HD. In a cube, the width, height, and depth are all the same, so this formula becomes 6Ssquared (S is any side).

Answer 8

Area is always given with units squared. You know this is wrong because it would have an s^2 in the answer.

The answer is 3s^2 (using calculus).

Answer 9

6s^2
