Question

A cube has a volume of 343 cm3.
What is the sum of the lengths of the
edges of the cube, in cm ?
How do I figure out the answer?

Answer 1

Answer:

112cm

Step-by-step explanation:

volume of cube = side cube

=343 cc

Side length of cube = 7cm

No of edges of cube =12

Length of each edge=7cm

the sum of the lengths of the

edges of the cube=No of edges of cube×Length of each edge

= 12×7=112cm

Answer 2

Volume of cube = a cube
Where a= side of the cube

343 = a cube
a= 7 cm

Side of cube = 7cm
Total no of edges =12

Sum of the lengths of the edges of the cube = no of edges * side of the cube
12*7 = 84 cm
