Question

A cube has a surface area of 96 square centimeters. How long is each face of the cube? A) 16 cm. B) 4 cm. C) 6 cm2. D) 16 cm4

Answer 1

Answer:

B

Step-by-step explanation:

HI, to calculate the surface area of a cube the formula is $6a^{2} =96$

$a^{2}=\frac{96}{6}=16$

$a=\sqrt{16}=4$

Hence the answer is B=4cm

Answer 2

Option B is rite because
SA = 6x^2 
96 = 6x^2 
16 = x^2 
x = 4
