How do You find the length,width and height of something?

Question

I'm stuck on homework.

Answer 1

Ask it nicely. If it's a woman, it's considered rude.

Answer 2

If you're talking about rectangular prisms, know that length x width x height = volume. So if you have the length (say 8) and the height (say 10) and the volume (say 320), then you can find the width:

8 x width x 10 = 320
80 x width = 320
width = 320/80 = 4

Answer 3

Decide on a unit, like the length of something. A Taylor would be 6 feet in this case, or the length of a digit on your index finger, or a standard unit like a centimeter or inch. You then see how many times this object can fit along a side. In the cases you gave, they would all be at right angles so that makes life easier. See how many of these units it is back, to the side, and up. That then is its measurements.

The Egyptian would use a particular length of a rope to measure out distances. The real trick is to divide the distance, or length, whatever you choose to call it, into as many whole parts as possible, then account for the piece at the end and a fraction of the whole, round to the nearest unit, or use a more accurate unit.

Answer 4

well, u can measure it, of course.
unless it is not an object but it is on paper. then, if it is drawn to scale, u can use the scale to figure out the exact lengths by setting up ratios:
a/b=c/d
a is the smaller unit
b is the amount the smaller unit represents
c is the measure on the figure in the smaller units
d is the measure of the actual thing.
cross multiply to get:
ad=bc
then, divide by a.
d=bc/a
and that's how u wud solve it
or, if u had a little info on the shape (like the volume, or the surface area, or something else), then u can use these formulas:
for a rectangular prism (that includes a cube)
v=l*w*h
sa=2((l*w)+(l*h)+(w*h))
for a square pyramid:
(1/3)(l*w*h)
not so sure about the surface area, but i believe u wud need a new variable for that.
hope that helps.

Answer 5

You measure?

Or if you have a volume and a couple of the other dimensions you can compute the third.

Volume = length x width x height

Answer 6

1. You can measure them
2. Someone can tell you what they are
3. Someone can tell you the volume and the area of the base of a rectangular prism. You can then compute the height as volume/area base.
4 If some one tells you the area of a square is 49, you can say reach side of the square is 7
5. And so on

Answer 7

It depend on what shapes your talking about; if it`s a rectangular prism the formula for that is V=L*W*H, if your trying to find the surface are the formula for that is sf=2wL+2wh+2hl

Answer 8

Use an appropriate measuring tool, like a ruler or tape measure, etc.

Answer 9

Hey Genius try measuring it!!!!
Your probably trying to find volume aren't you??
