May I add that the solution to the equation 2x^2 - x - 120 = 0 is that x = 8, not x = -7.5 as it is length so it cannot be negative.


yes i worked out the 2 number then i chose 8 !
what was the vase , i think i put down 300 but most likely wrong

There was one question about a cuboid and the angle AH makes with the base.....can't remember what i got exactly but i think it was like 62.5 or something around that
I got something like 102.4 for the vase, but how can the surface area be less than be volume? I was so confused. Pretty sure I was right, you square root the scale factor then cube it and divide.

Surface area is cm2 and volume is cm3, right?
So volume must be bigger because you cube it whereas for surface area you square it.
