How can I change the size of an object

How can i make an object bigger the a block

-Click on the object
-Click “click to edit”
-Click on the window on the left-hand side, just above the word “grid”. The window has a picture with two blue-ish squares and an arrow pointing towards the top-right corner.
(It’s also next to the window with the four blue arrows pointing in every direction)
-Once you clicked on it, look at the bottom of the window. You should see a “width” and “height” bar thingy to adjust. Adjust accordingly.
-You’re welcome.

thx alot
