Question

A cube has edges that are 3 cm long. If the length of the edges are doubled to make another cube, what's the difference in volume between two cubes?

Answer 1

We have,

Volume of first cube = (edge)³

= (3 cm)³

= 27 cm³

and, edge Length of new cube = 2 × 3 cm = 6 cm.

Hence, its volume = (6 cm)³ = 216 cm³

Difference in two volumes :-

216 cm³ - 27 cm³ = 189 cm³ Answer
