Question

A cube has side length of 2m. What is the surface area of the cube?

Answer 1

24 m²

Explanation:

we have to find the surface area of cube.

There are 6 sides of cube.All the sides are same.

hence,find the area of one side and the surface area of cube is product of area of all sides and 6.

let l is the length of one side.

Area of one side = l²

surface area of cube= 6l²

In question statement,we have given that

length= l= 2 m

Putting the given values in formula,we get

Surface area of cube= 6 (2)²

Surface area of cube= 6(4)

Surface area of cube = 24 m²

Surface area of cube is 24 m².

Answer 2

24 square meters.

Explanation:

The surface area of the cube consists of 6 congruent squares with side length of 2 m.

The are of one such square is

`2\cdot 2=4\ m^2.`

Hence, the surface area of the cube is

`6\cdot 4=24\ m^2.`
