So you want to make the equations equal Sasha's equation has a variable s Maggie's equation has s and h To get them equal you need to write them in terms of only s or h Look at the picture and we can see that s = 2h right? Side = 2 x height |dw:1549579202943:dw| So B and D are both wrong Next we need to plug it in correctly V = (1/6) s^3 V = (1/6) s^2 * (s) V = (1/6) s^2 * (2h)

Watch this: I'm going to try and get the area of a circle using rectangles: |dw:1549579845422:dw|
