Question

pls tell my friend all the answer if u got this answer​

Answer 1

Step-by-step explanation:

1) volume of a cube : side * side *side

= 0.03*0.03*0.03

=0.027m^3

2) if the height is halved then its volume would 1/2 times of its original volume

3)L.S.A of a cuboid = 2( length * breadth)height

= 2(2a*2b)2c

= 2*2*2*2(a+b)*c

16(a+b)c

so the answer is none of these

4) b) lateral surface area

5) volume of a cuboid = length*breadth*height

= 2a*3a*4a

= 24a^3

so b option is correct

6) $2\pi rh$= lsa

$2\pi*2r*2h$

$8\pi rh$

7)$2\pi *r*h$

$2*\pi *3*h=94.2$

2*22/7*3*h=94.2

44*3/7*h=94.2

h=94.2*7/3*44

h= 47.1*7/44

h=7.49

so none of these is the answer

8) 8 times

for ex. if the side of a cube is 2cm

the volume would be 2*2*2=8

if the side would be doubled then the side = 4cm

volume = 4*4*4=64

the volume got just doubled of it

9)c)3root3

10)none of these

hope u got it....

Answer 2

Answer:

volume of a cube : side * side *side

= 0.03*0.03*0.03

=0.027m^3

4) b) lateral surface area

5) volume of a cuboid = length*breadth*height

= 2a*3a*4a

= 24a^3

so b option is correct

6) 2\pi rh2πrh = lsa

2\pi*2r*2h2π∗2r∗2h

8\pi rh8πrh

7)2\pi *r*h2π∗r∗h

2*\pi *3*h=94.22∗π∗3∗h=94.2

2*22/7*3*h=94.2

44*3/7*h=94.2

h=94.2*7/3*44

h= 47.1*7/44

h=7.49

so none of these is the answer

8) 8 times
