Question

Here is a picture of a cube, and the net of this cube. What is the surface area of this cube?

Answer 1

Answer: 864mm

Explanation:

A cube has 6 faces and each side of the face is 12mm. Cubes are square, so each of the sides is the same value.

We take 12mm x 12mm = 144mm as an area for ONE side.

There six sides, so take 144 x 6 = 864

The area is 864mm

34.0157 (inches)

86.4 (cm)
