A cube has a surface area of 24 units². Find the length of the side. Remember, the formula for surface area of a cube is SA = 6s²

a) 2 units
b) 4 units
c) 6 units
d) 1 unit​


Sagot :

Answer: A) 2 units

Step-by-step explanation:

Since SA = 6s^2, then

24 = 6s^2.

We can divide both sides by 6:

s^2 = 4.

Therefore, s = 2.

Given :- surface area = 6 s² = 24 units ²

s = side of the cube

so by putting the values:-

[tex]surface \: area = 6 {s}^{2} \\ 24 = 6 \times {s}^{2} \\ \frac{ \cancel{24} {}^{ \: \: 4} } { \cancel{6} } = {s}^{2} \\ 4 = {s}^{2} \\ \sqrt{4} = s = 2 \: units[/tex]

Option A :- 2 Units
