Answer:
Option C is correct
600 [tex]in^2[/tex]
Step-by-step explanation:
Surface area of cube(S) is given by:
[tex]S = 6a^2[/tex] ....[1]
where, a is the side length of a cube.
As per the statement:
A cube with side length 9.9 in.
⇒a = 9.9 in.
Substitute in [1] we have;
[tex]S = 6 \cdot (9.9)^2 = 6 \cdot 98.01 = 588.01 \approx 600 in^2[/tex]
Therefore, the estimate the surface area of a cube is, 600 [tex]in^2[/tex]
