The dimensions of a box are measured to be 18.4 inches by 17.92 inches by 26 inches. the volume of the box can be found by multiplying these three dimensions. what is the volume of the box expressed to the correct number of significant figures?

The volume of the box is 8.6 × 10³ in².

V = lwh = 26 in × 18.4 in × 17.92 in = 8.6 × 10³ in²

Note: The answer can have only two significant figures because that is all you gave for the length of the box.

practical process described pest part of scientific investigation.

because practical knowledge is powerful then therotical knowledge.

it can be observed without changing the identity of the object.

it depends on what substance you're talking about as well as many other factors. in quantum mechanics, the observation of particles affects the observers ability to measure certain properties. for example: you can know the velocity of a particle, but you can't know it's position; or you can know it's position, but not it's velocity. it's like trying to find out where a grain of sand is by throwing other grains of sand at it. once you find out where it is, it's been moved. it's also like trying to find an answer to the question of whether or not a tree falling in a forest makes a sound if nobody is there to hear it. paradoxically, the only way to find out is to be there and hear it.
