Question

The total surface area of a cube with side 8 m is:

Answer 1

Answer:

surface area of cube is 6a²

therefore surface area of cube with side 8m is = 8³ m³= 512m³

hence your answer is 512m³

Answer 2

Given : A cube with side 8 m.

To find : The total surface area.

Solution :

We can simply solve this mathematical problem by using the following mathematical process. (our goal is to calculate the total surface area)

Here, we will be using the following the mathematical formula.

Total surface area of a cube = 6 × (side)²

By, putting the available data in the above method mathematical formula, we get :

Total surface area of the cube = [6 × (8)²] m²

or, Total surface area of the cube = 384 m²

(This will be considered as the final result.)

Hence, the total surface area of the cube is 384 m².
