how much water?
Typical engineer. Instead of giving you the amount of water in
terms of a measure that might actually make some sense, like
cups or spoonfuls or gallons, he’s talking about cubic meters. So,
how much is 3 cubic meters of water? A bathful? A pondful? A
swimming poolful?
Let’s start by think about what just 1 cubic meter actually is:
Is 3 cubic meters of water a lot or a little?
A cube-shaped container with length, width, and
depth all of one meter holds exactly one cubic
meter of water.
So 3 cubic meters of water is the volume of water
you could store in three of those one meter cubes:
1m
1m
1m
Length
Width
Depth
Volume of a cube = length x width x depth

3 cubic meters =
Cubic meter = 1m x 1m x 1m

regular polygons
That’s true.
In fact, thinking about cube shapes can only take us
so far, because, aside from the square-shaped one,
the hot tub range isn’t made out of cubes.
OK—stop right there! I don’t know
how closely you’ve looked but I
don’t see any hot tubs that look like
they’re made out of CUBES.
How do the hot tubs compare to a cube?
Like a cube, all the hot tubs have a uniform depth. They
also have straight sides at a right angle to the base. But for
most of the shapes of hot tub, calculating the volume ...
