This toy box is designed backwards from a store-bought part, and that's its best idea: the bottom is a pre-glued 36" x 15-1/4" project panel, sold off the shelf, so the one wide flat panel in the build — the one you'd otherwise have to glue up or cut from a plywood sheet — is a line item, not a task. Everything else is 1x boards.
The legs are the visual trick. Each is a 1x3 face-nailed to a 1x2, making an L that reads as a solid corner post but comes out of cheap flat stock. Plank the sides between the legs with 1x4s, glue the long seams as you go, and the walls end up far stiffer than a stack of face-nailed boards has any right to be.
One thing in this build is safety-critical rather than structural: the lid support. A toy box lid is heavy, and the person opening it is three years old with their fingers on the rim. Buy a proper toy-box lid support — the kind that holds the lid at any position — and install it per its instructions. It's a few dollars, and it is not optional in any build that will actually hold toys.

Glue and nail each 1x3 leg piece to a 1x2 leg piece with the outside edges flush, a brad about every 6". The L-profile is what makes flat stock read as a corner post.
Build all four, then stand them together and check they're the same height — a proud leg now is a rocking box later.
Glue and nail a 33" plank across the tops of two legs, top and outside edges flush. Orientation matters: the wider 1x3 leg face goes on the FRONT of the box, the 1x2 face on the ends. Get one leg backwards and the planking won't land flush at that corner.
Add the remaining long planks below the first, working downward. Run glue along the long seam between planks as well as on the legs — those glued edges are what turn four separate boards into one stiff panel.
Attach the 13" end planks the same way, starting at the top and working down, glue in every seam, brads into the legs. You now have the full box shell, open top and bottom.
Measure both diagonals across the box bottom. If they don't match, push the long corners toward each other until they do — the box is only square when the numbers are.
Screw the 1x8 bottom boards on with the self-tapping screws. Then, for strength, also glue and nail through the outside of the legs into the edges of the bottom boards. The bottom carries the toys; the extra fasteners keep it from ever sagging out.
Glue and nail the 36" 1x2 across the top back edge. It finishes the rim and gives the hinges solid wood to bite into instead of plank end grain.
Attach the project-panel lid with the two 3" hinges into the top trim.
Now the part that matters: install the toy box lid support so the lid physically cannot slam. Test it by letting go of the lid at every height — it should stay put or drift down slowly. Stick felt pads or bumpers on the rim to quiet the close.
Sand every edge and corner round before you call it done. The finish is your call; if you paint, use a low-VOC paint and let it cure fully before toys go in.
