What is the surface area of the cube?

64 mm²

192 mm²

384 mm²

512 mm²

cube with length, width, and height labeled 8 millimeters

C) 384 mm²

Step-by-step explanation:

A cube has 6 faces, all squares

Area of each face: s²

8² = 64

Surface area

6 * 64

384 mm²

All the side lengths of a cube are the same.

A cubes as 6 sides (faces).

Find the area of one side.

8 * 8 = 64 mm²

Multiply by the number of sides.

64 * 6 = 384 mm²

Therefore, the surface area of the cube is 384 mm²

Best of Luck!
