in a cuboid dimension 40 centimetre into 30 centimetre into 5 centimetre how many cubes of edge 5 centimetre can be placed
it's 48 cubes because if you take out the volume of cuboid and then find volume of cube after that if you will divide volume of cuboid by volume of cube then you will get the result as 48

Answer:
To find the number of cubes we need to find the volume of the Cuboide
Vol(Cuboide)= 30 x 40 x 5 = 6000cm³
vol (Cube)= a³=5³= 125
Now total cubes which can fit is 6000/125
=> 48 cubes
Great work

Answer:
48 cubes of edge 5 cm can be placed.
Step-by-step explanation:
Given: Dimensions of cuboid:
Length = 40 cm
Breadth = 30 cm
Height = 5 cm
Formula:
Volume of cuboid = (lbh) cubic unit
Volume of cube = a³ cubic unit
Let the x number of cubes of edge 5 cm can be placed.
According to the question:
(5)³ × x = 40 × 30 × 5
→ 125x = 6000
→ x = 6000/125
→ x = 48
∴ Number of cubes of edge 5 cm = 48
Splendid
