Question

A solid cube of edge 14 cm is melted down and recast into smaller and equal cubes each of edge 2 cm, then the number of smaller cubes obtained is 343.

• A. True
• B. False

Answer 1

The correct option is A True

Volume of solid cube = a${}^3$

= 14${}^3$ = 2744 cm${}^3$

Volume of small cube = a${}^3$

= 2${}^3$

= 8 $c{m}^3$

No. of cubes = $\frac{2744}{8}$

= 343
