Rectangular Prism Net Generator

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.

What does a rectangular prism net look like?
A rectangular prism net has 6 rectangles in a cross pattern: 4 connected side faces with 2 attached faces. Different arrangements are possible; this calculator uses a common cross net that keeps opposite faces easy to identify.
What is the surface area of a rectangular prism?
SA = 2(lw + lh + wh) where l is length, w is width, and h is height. Each pair of opposite faces has the same area.
Can I print this net?
Yes! All dimensions are exact. Save via share/export, print at any scale, and add glue tabs for assembly.
How many nets does a rectangular prism have?
A rectangular prism has 54 distinct nets (11 different hexomino arrangements multiplied by variations from different face dimensions). The cross pattern shown here is the most common and easiest to fold.
What can it graph?
It can plot explicit, implicit, and parametric functions, add points and geometry, and animate sliders on the same graph.
Can I use voice or a photo?
Yes. You can talk to the tutor, upload a worksheet or handwritten problem, and let the graph update from that input.
Will it explain the steps?
Yes. The AI explains what it is drawing and why, so you see the answer on the graph instead of getting only a final number.
