Answer 2

Answer:

The Number of packets that will go in the carton are 350.

Step-by-step explanation:

Given :

Size of one matchbox = 4 cm × 2.5 cm × 1.5 cm

Number of packets = 144

Dimensions of the Carton = 150 cm × 84 × 60 cm

To find :

The number of packets of 144 matchboxes fixed in the carton.

Solution :

★ Volume of the one matchbox :

$\boxed{\sf{Volume = Length \times Height \times Breadth}}$

$\sf{\implies} \: 4 \times 1.5 \times 2.5 \\ \\ \sf{\implies} \: 4 \times 3.75 \\ \\ \sf{\implies} \: 15 \: {cm}^{3}$

Volume of one matchbox = 15 cm³

$\rule{300}{1.5}$

★ Volume of packet containing 144 boxes -

Multiply the volume of one matchbox by 144.

$\sf{\implies} \: 15 \times 144 \\ \\ \sf{\implies} \: 2160 \: {cm}^{3}$

Volume of the packet which contains 144 matchboxes is 2160 cm³.

$\rule{300}{1.5}$

★ Number of above mentioned packets that fit in the carton -

Volume of the Carton =

$\sf{\implies} \: 150 \times 84 \times 60 \\ \\ \sf{\implies} \: 756000 \: {cm}^{3}$

Number of packets =

Divide the Volume of carton by the volume of each packet.

$\sf{\implies} \: \dfrac{756000}{2160} \\ \\ \sf{\implies} \: 350$

The number of packets = 350

$\therefore$ The Number of packets that will go in the carton are 350.
