Well , i have 2 questions here :

part a :

I'm asked to find the volume bounded by plane y +z = 1 , y = (x^2) , xy plane and yz plane

part b :

I'm asked to find the volume bounded by plane y +z = 1 , y = (x^2) ,and z = 0 ...

the ans given for part a is 4/15 , for part b is 8/15

However , i cant imagine the solid bounded by the region in part b ....

For part a , i suspect the ans is wrong ...
