Question

find surface Area of cube with length 3centimeter (surface area =4square)​

Answer 1

Answer:

A=6a2

Step-by-step explanation:

Explanation:

The surface area of a cube = 6a2 where a is the length of the side of each edge of the cube. Put another way, since all sides of a cube are equal, a is just the lenght of one side of a cube.

We have 96 = 6a2 → a2 = 16, so that's the area of one face of the cube.

Solving we get √16, so a = 4
