What is the volume of a metal block 3cm long by 2cm wide by 4cm high? What would be the volume of a block twice as long, wide, and high?

Volume of a metal block = 24 cm^3

Volume of a block twice as long, wide and high = 192 cm^3

Explanation:

Volume of a block is measured in l*w*h and in the first block, the sides are 3, 2 and 4 and 3*2*4 = 24

Second block, just double each of the lengths to get 6*4*8 = 192

Volume = l×b×h

Length= 3cm

Breadth = 2cm

Height = 4cm

Volume = 3×2×4

= 24cm²

When length, breadth and height is doubled

Length = 3×2

= 6cm

Breadth = 2×2

= 4cm

Height = 4×2

= 8cm

Volume = l×b×h

Volume = 6×4×8

= 192cm³

Also if the length , breadth and height is doubled then the voulme increases 8 times.

i dont know but

explanation:

whoever your teacher is, deserves a raise for using pokemon as an example

the minimum constant speed at which she can catch the train is 2.7 m/s

given:

acceleration = 0.6

time = 4.5 s

to find:

velocity = ?

formula used:

from 1st kinematic equation we get,

v = u + at

u = initial speed of train = 0 m/s

v = final speed of the train

a = acceleration of the train

t = time

solution:

from 1st kinematic equation we get,

v = u + at

u = initial speed of train = 0 m/s

v = final speed of the train

a = acceleration of the train

t = time

v = 0 + (0.6 × 4.5)

v = 2.7 m/s

the minimum constant speed at which she can catch the train is 2.7 m/s
