Step-by-step explanation: do length x base x height to get your answer
If you know that
, then you know right away

###
Otherwise, you can derive the same result. Let
, so that
.
is bounded, so we know
. For these values of
, we always have
.
So, recalling the Pythagorean theorem, we find

Then

as expected.
2x2x2x2x2=32
32x2=64
2x2x2x2x2x2=64
2^6 is your answer
