Looking for a cross sections quiz? Then this Grade 7 quiz on Cross Sections of Prisms and Pyramids asks 10 multiple-choice questions with instant feedback. Ten multiple-choice questions check naming cross sections of prisms and pyramids and computing their dimensions and areas. Each wrong choice mirrors a real slip, such as thinking every pyramid slice is a triangle, so picture the plane and the solid before you answer.
Standards: 7.G.A.3 · Level: Grade 7
What this Cross Sections of Prisms and Pyramids quiz checks
- A cross section is the two-dimensional face where a plane meets a solid.
- Every parallel or perpendicular slice of a rectangular prism is a rectangle.
- A pyramid slice parallel to its base is a rectangle similar to the base, scaled by distance from the apex ÷ height.
- A vertical pyramid slice is a triangle through the apex and a trapezoid otherwise.
The 10 questions of the quiz
- A flat cut runs parallel to the bottom of a box-shaped prism. Which shape appears on the cut face?
- A flat cut runs parallel to the bottom of a pyramid with a rectangular base. Which shape appears on the cut face?
- What is the cross section shown in the figure?
- What is the cross section shown in this figure?
- A box measures 12 in by 5 in by 8 in. An upright cut runs parallel to the 12-by-8 side. What is the area of the cut face?
- A model pyramid has a 15 in by 9 in base and is 12 in tall. A flat cut parallel to the base passes 4 in below the apex. What are the sides of the slice?
- Which cross section can a rectangular prism never have when cut parallel or perpendicular to its base?
- A pyramid is cut parallel to its base halfway between the base and the apex. How does the area of the slice compare with the base area?
- A pyramid has a 10 in base and a height of 8 in. A vertical plane through the apex is parallel to the 10 in edge. What is the area of the triangle?
- A tank has a 20 in by 10 in base and is filled with water 6 in deep. What is the area of the water’s surface?
