# 1617-257/Homework Assignment 8 Solutions

Problem A. Let $Q=[0,1]^3$ and let $f\colon Q\to{\mathbb R}$ be given by $f(x,y,z)=1$ if $x, and $f(x,y,z)=0$ otherwise. Compute $\int_Qf$. (This problem is merely about computations. You may assume without proof that $f$ and all other functions you may encounter along the computation are integrable).
