Volume of a Pyramid + Volume of a rectangular prism = Total Volume

anonymous · Answer

that is the compostite figure above

anonymous · Answer

oh okay so i just have to add them and not do anything else to them

anonymous · Answer

$\large \frac{(Base_{area})^2(height_1)}{3}$ + L*W*H$_2$ = total volume in units$^3$

anonymous · Answer

Careful though, there's the height of the pyramid, and the height of the box under it

anonymous · Answer

If you're trying to find volume of both shapes combined, then yes that's addition.  :-)

Write units next to all your numbers, you should see everything come out as cubed units as you go about doing the arithmetic.  Always remember the units!  :-D  Got it?
