You must first find the area of on triangular base of the prism. Once you have that, multiply the area of the triangle with the length of the prism.

answer: domain and range mean all possible values of x and y that could be substituted to the inequality. a solution means all possible values that make the inequality statement true. so while the range is still all real numbers, the solution is the shaded area, for which y will always be greater than the line of the function.
