What is the surface area of the cube?<br>A. 64 mm2<br>B. 192 mm2<br>C. 384 mm2<br>D. 512 mm2​
ivanzaharov [21]

Answer:

C. 384 mm2

Step-by-step explanation:

In order to find ONE side, you would multiply 8x8 (in this scenario at least).

You would then get this:

8mm x 8mm = 64mm2

But we're not done yet!

In order to find all six sides, you need to multiply the last number/area by six

You would then get:

64 x 6 sides = 384mm2

Hope this helps!
