Question

How many cuboidal-shaped chalks each of volume 8 cm3 can be packed in a box measuring 12cm x 7cm x 2cm?

Answer 1

Answer:

The total number of cuboidal-shaped chalks are 21 chalks.

Step-by-step Explanation

To Find -

• The number of cuboidal-shaped chalks.

★ Solution :-

Given that,

• Volume of one cuboidal-shaped chalk = 8cm³
• Dimensions of box = 12cm*7cm*2cm.

The volume of the cuboidal box is :-

As we know that,

Volume of cuboid = lbh cubic units.

Where,

l = length, b = Breadth and h = height.

➝ lbh

➝ l*b*h

➝ 12cm*7cm*2cm

➝ [12*7*2]cm³

➝ 168cm³

∴ The volume is 168cm³.

Now,

• The number of chalks are :-

According the question,

Number of chalks = Volume of box/Volume of chalk.

➝ Volume of box/Volume of chalk

➝ 168cm³/8cm³

➝ 168/8

➝ 21 chalks.

Hence,

The total number of chalks are 21 chalks.
