(iv) Find the distance between the points R(0, -3) and S(0,5/2)
Answers
Answer:
distance ,= sq.root ( 0-0)2+(5/2+3)2
= sq.root (11/2)2
11/2
Answer:
Number of cubes which can be placed in given cuboid is 450.
Step-by-step explanation:
Given :-
Dimensions of cuboid are 60 cm x 54 cm x 30 cm.
Side(edge) of small cube is 6 cm.
To find :-
Number of small cubes which can be placed in the given cuboid.
Solution :-
Here, If we want to place small cubes in cuboid then first we need to know volume of cuboid and volume of cubes.
So,
We know,
Volume of cuboid = lbh
[l is length, b is breadth and h is height of cuboid]
l = 60 cm
b = 54 cm
h = 30 cm
Put all values in formula :
\longrightarrow⟶ Volume = 60 × 54 × 30
\longrightarrow⟶ Volume = 97200
Volume of cuboid is 97200 cm³.
And,
Volume of cube = (edge)³
Edge = 6 cm
Put edge in formula :
\longrightarrow⟶ Volume = (6)³
\longrightarrow⟶ Volume = 216
Volume of one small cube is 216 cm³.
Now,
\sf Number \: of \: cubes = \dfrac{Volume \: of \: cuboid}{Volume \: of \: one \: cube}Numberofcubes=VolumeofonecubeVolumeofcuboid
\leadsto⇝ 97200/216
\leadsto⇝ 450
\bold{\therefore}∴ Number of cubes which can be placed in given cuboid is 450
