Question
A box is in the form of a cube with an edge of 7 cm long. Calculate the total length of the edges
- 24
- 64
- 44
- 84
Hint:
There are 6 faces and 12 edges of cube. And all edges are of equal length.
The correct answer is: 84
Given :- edge length= 7 cm
According to question,
Let edge length of a cube = l
Since, cube has 12 edges.
So, sum of length of edges =12 l
Hence formula for the sum of edge length = (12 
one edge length)
= 12(7)
= 84
Therefore, the correct option is d) 84
Therefore, the correct option is d) 84
