Join to two tables

I have created three table using with the following code:

CREATE TABLE Invoices (    invoiceID nvarchar(5) NOT NULL PRIMARY KEY,     invoiceDate date, );CREATE TABLE ContainsItems (    invoiceID nvarchar(5) REFERENCES Invoices(invoiceID),    itemID nvarchar(5) REFERENCES Items(itemID),    itemQuantity numeric(2, 0));CREATE TABLE Items (    itemID nvarchar(5) NOT NULL PRIMARY KEY,    itemName nvarchar(20),    unit nvarchar(20),     pricePerUnit float);

For a given Invoice (invoiceID), how am I am to query a list all it's Items (itemNames) and their corresponding price per unit, and the number of units (itemQuantity) invoiced?

I've been trying this all night and got stumped.
