Solution

Dimensions of tea-packet
= $10 c m \times 6 c m \times 4 c m$ .
$∴$ Volume = $10 c m \times 6 c m \times 4 c m$ .
Dimensions of box
= $50 c m \times 30 c m \times 0.2 m$
= $50 c m \times 30 c m \times 20 c m$
Volume = $50 \times 30 \times 20 = 30000 c m^{3}$
$∴$ Number of tea-packets to be kept
= $\frac{30000}{240} = 125$
