Hello Barry,
For achieving that you need, to build customized visual force page and create Visual Force Tab for the page.

For more details refer the following question posted.

Hi Barry

Try the below custom visual force code and class

VF:
<apex:page controller="opportunityList2Con">
    <apex:pageBlock >
        <apex:pageBlockTable value="{!opportunities}" var="o">
            <apex:column value="{!o.Name}"/>
            <apex:column value="{!o.Amount}"/>
        </apex:pageBlockTable>
        
        <apex:pageBlockSection >
            <apex:pageblocksectionitem >
                <apex:outputLabel value="Grand Total" style="font-weight: bold;"></apex:outputLabel>
            </apex:pageblocksectionitem>
           
            <apex:pageblocksectionitem >
                <apex:outputLabel style="margin-left: 285px !important;font-weight: bold; " value="${!total}"></apex:outputLabel>
                
            </apex:pageblocksectionitem>
        </apex:pageBlockSection> 
 
    </apex:pageBlock>
    
</apex:page>



Class:
 
public class opportunityList2Con {
    // ApexPages.StandardSetController must be instantiated
    // for standard list controllers
    public ApexPages.StandardSetController setCon {
        get {
            if(setCon == null) {
                setCon = new ApexPages.StandardSetController(Database.getQueryLocator(
                    [SELECT Name,CloseDate,amount,tot__c,Account.Total_Am__c FROM Opportunity ]));
            }
            return setCon;
        }
        set;
    }

    // Initialize setCon and return a list of records
    public List<Opportunity> getOpportunities() {
        return (List<Opportunity>) setCon.getRecords();
    }
    public double getTotal(){
        list<opportunity> totalopp = [select amount,tot__c,Account.Total_Am__c FROM Opportunity];
        double grandtotal = 0;
        for(opportunity opp : totalopp){
            if(opp.amount!=null)
            grandtotal  =grandtotal + opp.amount;
        }
        return grandtotal;
    }
}
