Question

A cuboidal candle is $10cm$ long and $8cm$ wide. How height it must be made to hold $480c{m}^3$ of wax?

Answer 1

Length $=10cm$

Breadth $=8cm$

Volume $=480c{m}^3$

$l\times b\times h=480$

$10\times 8\times h=480$

$h=\frac{480}{80}$

$h=\frac{48}{8}$

$h=6m$

$\therefore$ The height must be $6m$ to hold $480c{m}^3$ of wax
