Column width issue

My site: https://vandasurf.com/?page_id=99

I understand i have a layout issue, the column is too narrow. I have tried to widen it but I’m inserting the text in the wrong place or have it wrong. Can you help?

Ive tried inserting
.default-pagetemp #content {
width: 100%;
}

#wpc-col-2 {
width: 715px !important;
}

under the layout section. Do i have to delete something else in there as well? Or am I in the wrong section?

My layout content reads like this.

/* Layout
————————————————————– */
#main {
clear: both;
width: 100%;
margin: 0 auto;
position: relative;
}
.page-template-fullwidth #content { width: 100%; }
.content-wrap {
float: right;
width: 79.78723404255319%; /* 750 / 940 = 0.7978723404255319 */
}
.page-template-fullwidth .content-wrap { width: 100%; }
#content {
float: left;
width: 62.66667%; /* 470 / 750 = 0.6266666666666667 */
margin: 0 0 30px 0;
}
.aside {
float: left;
width: 17.02127659574468%; /* 160 / 940 = 0.1702127659574468 */
}
#sidebar-primary {
float: left;
width: 100%; /* 160 / 940 = 0.1702127659574468 */
}
#sidebar-secondary {
float: right;
width: 33.33333333333333%; /* 250 / 750 = 0.3333333333333333 */
}
.wrap {
max-width: 940px;
margin: 0 auto;
position: relative;
}
#comments-template { clear: left; }

I’d be happy to get rid of the left sidebar (Facebook feed) on all the pages and just leave it on the home page but I can’t figure that either! That might give me more room?
Thankyou!
