@TechnicianExpert  this is it the figure

anonymous · Answer

well the area of the base or midsection should be 48in.

anonymous · Answer

which is ABCD

anonymous · Answer

but how?

anonymous · Answer

can you guide me on how to do it?

anonymous · Answer

well the area of the base is length*width mainly because it is a rectangle

anonymous · Answer

but its not 48 in^2 coz the answer is 20 in ^2

anonymous · Answer

which then all you do is multiply 12*4 and you get 48inches
then to find the volume you 1/2*base*height which should be 1/2*12*6 and the answer for that should be 36
