How much more would you weigh if you you were to double in size?

Answer 1

it sort of depends how you define size; if we think of a human roughly as a cylinder, your volume is pi*r^2*h where r is a measure of your radius and h of your height; if you mean doubling your radius without changing your height, then you would increase your weight four fold, if you mean doubling in all dimensions (which is hard to imagine) your weight would increase 8 fold

Answer 2

Let's look at it mathematically:

The equation for the weight of a person on earth is:

W = mg, where g is the acceleration due to gravity on Earth.

Ok, say we double the mass:

W = (2m)g

Using the commutative property of multiplication, we get:

W = 2(mg)

If you plug in W for mg, you get:

2W = 2(mg)

So, you weigh twice as much.

Answer 3

If you were twice as tall you would weigh 2x2x2 times as much = 8 times as much.

Answer 4

depends. If nothing else changes then nothing. Weight isn't about size, really. I mean, a giant ball of cotton the size of a house wouldn't weight more than a small one-ton metal ball.

Answer 5

As much as you weigh now.

Answer 6

density=mass/volume

Mass is directly proportion to volume in1:1
so if volume double ,mass double.
volume to length is in cubic proportion
Vbig/vsmall=(lenthbig/lengthsmall)^3
therefore if length is double , volume is 8 times more, since volume is in linear proportion to mass , there fore the mass is 8 times more if size is double

Answer 8

Twice as much
