Answer 2

Given:

A chalk box of volume $24cm^{3}$

To find:

The dimensions of the chalk box from the given options.

Solution:

Chalk box is in the shape of a cuboid.

Volume of cuboid = length $(l)$ × breadth $(b)$ × height $(h)$

Consider option (i).

$l=5cm,b=1cm,h=3cm$

$V=24$ (given)

and, $V=l*b*h$

$V = 5*1*3=15\neq 24$

∴ Option (1) is not correct.

Consider option (ii)

$l=10cm,b=4cm,h=10$

$V=10*4*10=400\neq 24$

∴ Option (ii) is not the answer

Consider option (iii)

$l=2cm,b=2cm,h=6cm$

$V=2*2*6=24=24$

∴ Option (iii) is the correct choice.

The dimensions of the chalk box with volume 24cm³ are 2cm×2cm×6cm. Option (iii) is the correct answer.
