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.

the answer is ampere

the ampere is used to measure electricity. an ampere is a unit of electric current equal. a unit of measure for the flow of current in a circuit. one ampere is the amount of current flow provided when one volt of electrical pressure is applied against one ohm of resistance.
