Sum of lengths of all edges of a cube is 84 cm, find its volume?
1). 686 cubic cms
2). 343 cubic cms
3). 171.5 cubic cms
4). 514.5 cubic cms
Total Number of Edges in a cube is: 12
Sum of all edges = 84
Length of one edge is $= \frac{84}{12} = 7$
Volume of cube is $7^3 = 343$
Hello, 343 cubic cms is correct
