Uploaded by Putri

Worksheets with an answer-key style layout practice 3D geometry for square pyramids and rectangular pyramids. Students compute surface area using base area, perimeter, and slant height, and find the volume of rectangular pyramids rounding answers to two decimals. Multiple problems use different units (e.g., cm, mm, m, ft, in) and provide example formulas and completed solutions for comparison.
