Can you just help me through it?

mathstudent55 · Answer

You must be able to find the formulas you need. Do you have a text book?

mathstudent55 · Answer

Ok, here are the formulas.

$\Large V_{cube} = s^3$

where s = side of cube

$\Large V_{pyramid} = \dfrac{1}{3}Bh$

where B = area of the base,. and 
h = height of the pyramid
