Question

What is the surface area of the cube? Drag and drop the correct surface area to match the cube. cube with edge length = 3.2 m A 12.8 B 19.2 C 51.2 D 61.44

Answer 1

6 sides x 3.2x3.2 = 61.44 ==> D

Answer 2

Answer:
`61.44\ m^2`

Explanation:

It is given that the side length of cube = 3.2 m

The surface area of a cube is given by :-

`\text{Area of cube}=6(side)^2`

Therefore, area of the given cube will be :_

`\text{Area of cube}=6(3.2)^2\\\\\Rightarrow\ \text{Area of cube}=6(10.24)\\\\\Rightarrow\ \text{Area of cube}=61.44\ m^2`

Hence, the surface area of the cube =
`61.44\ m^2`
