What are your choices?
What did you not like about my answer yesterday?
my choices are:
A. v=4b^4h^2 divided by 3
B. v=2b^4h^2 divided by 6
C. v=4b^2h divided by3
D. v=2b^2h divided by 3
E. v=4b^4h^2 divided by 6.
this is for ms.sue.
Ted, neither in todays nor in yesterdays post did you give any dimensions.
Your choices of answers suggest that the base had side b and the height was h
so matching my answer of (4/3)x base area x height
would be C. 4b^2h/3 or (4/3) b^2 h
