Question

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

Answer 1

Surface area of cube = 6(a)^2
= 6(8)^2
= 6(64)
= 384 MMS^2

Answer 2

Answer:

512 mm²      

Step-by-step explanation:

Given : length, width, and height labeled 8 millimeters

To Find: What is the surface area of the cube?

Solution:

Side of cube = 8 mm

Formula of total surface area of cube = $6a^{2}$

Where a is the side of cube.

So, the surface area of given cube = $6(8)^{2}$

                                                          = $6\times 64$

                                                          = $512 mm^2$      

Hence the surface area of the cube is 512 mm²
