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.
