Unfold a box into 6 rectangles — with exact dimensions and fold lines
A rectangular prism net (box net) consists of 6 rectangles arranged in a cross or T pattern. Enter width, height, and depth — the calculator draws the complete net with fold lines, dimensions, volume, and surface area.
The cross pattern places 4 side faces in a column with 2 remaining faces extending left and right. This layout makes it easy to identify which faces are opposite each other and how they connect when folded.
Every net is printable with exact measurements — use the share/export button to save, then print and fold. Real-world boxes like cereal boxes, gift boxes, and shipping cartons all use rectangular prism nets in manufacturing.
