Surface Area From Nets of Trapezoidal Prisms

Begin with the face-by-face sheets, then use the nets and formula sheets. The paint and wrap sheet suits a project or review day.

Find the six face areas on a net of a trapezoidal prism and add them for the total surface area. The directions on the page read: Find the area of each lettered face and write it in the table. The two trapezoids match, and the shorter parallel side of each one is as long as the width of face E. Add all six areas for the total. Show your work in the box. An answer key is included.

Yes, both. We made it for 7th grade geometry, and it works the same at home or at school. At home, a student can work through it alone and then go over it with you, which shows quickly what is solid and what needs another look. In class it works as independent practice, homework or a warm-up, and you can print one copy or a full set.

Find the area of every face and add them. For a rectangular prism, that means six faces, or use SA = 2lw + 2lh + 2wh.

Find the area of the base B, then multiply by the prism height h, so V = Bh. The Volume of Right Prisms With Polygon Bases worksheet practices this.

A net shows every face of a solid laid flat, so students can find each face area and add them. The nets worksheets cover triangular prisms, pyramids and trapezoidal prisms.

Yes. All 14 worksheets in this group have answer keys.
