This is the code I used previously to edit the page to my liking:

/* this code edits the size of the product page's product picture/info*/
.content-left.page-with-sidebar.col-sm-8.col-md-9.col-lg-8{
    width: 1400px;
    height: 500px;
    padding: 0px;
    float: left;
}

/* this code edits the pricing box on the product page*/.content-right.col-sm-4.col-md-3.col-lg-3.col-lg-offset-1{
    margin: 0px;
}

/*this makes the product page the right size*/
#container_full{
    width: 1400px;
    height: 700px;
    margin: 0px;
    padding: 0px;
}
