Explanation:

960 identical packets of soaps each of 10 cm long and 5 cm wide can be kept inside a rectangular box of dimension 80 cm*60 cm*40 cm, what is the height of each packet of soap ?

_____________________________________

★ Solution :-

Given,

» Number of packets of soap = n = 960

» Length of each packet of soap = l = 10 cm

» Breadth of each packet of soap = b = 5 cm

» Length of each packet of soap = L = 80 cm

» Breadth of each packet of soap = B = 60 cm

» Height of each packet of soap = H = 40 cm

• Let the height of the packet of soap be 'h' cm. Then, using the concept, we get,

⟹ l × b × h × n = L × B × H

⟹ 10 × 5 × h × 960 = 80 × 60 × 40

⟹ 50 × 960 × h = 80 × 60 × 40

\: \: \: \: \huge{\longrightarrow \:\:\bold{h \: = \: \dfrac{80 \: \times \: 60 \: \times \: 40}{50 \: \times \: 960}}}⟶h=

50×960

80×60×40

⟹ h = 4 cm

\: \: ➮ \: \: \underline{\boxed{\sf{\red{Hence, \: the \: height \: of \: each \: packet \: of \: soap \: is \: \underline{4 \: cm}}}}}➮

• Volume of cuboid = (side)³

• Volume of cylinder = πr²h

where, r is radius and h is height.

• Volume of cone = ⅓(πr²h)

• Total Surface Area of Cuboid = 2(lb + bh + lh)

• Total Surface Area of Cube = 4a²

• Total Surface Area of cylinder = 2πr(r + h)

Height of each packet of soap is 4 cm

hope it helps

Answer 2

Answer:

Given :

960 identical packs of soaps each of 10 cm long and 5 cm wide can be kept in a rectangular box of 80 cm * 60 cm * 40 cm.

To find :

Height of each packet.

Solution :

Now as 960 packets of soap can be kept inside that cartoon, so :

Volume(cartoon) = n * Volume(each packet of soap)

Here, n = number of soap packets.

Let the height of each packet of soap be x cm.

Volume of cartoon = l * b * h

Volume of each packet of soaps = l * b * h

According to question,

⇒ 80 * 60 * 40 = 960 * 10 * 5 * x

⇒ 192000 = 48000 * x

⇒ x = 192000/48000

⇒ x = 4 cm

∴ Height of each packet of soap = 4 cm......
