Rectangular Pyramid

Use this worksheet to practice finding the Volume and Surface Area of a Rectangular Pyramid. Adjust the height, length, and width using the labeled sliders. Answer the questions below. The multi-colored switches can be used to check your work.
1. Find the volume of each Rectangular Pyramid to the nearest cubic unit.[br]a. height 9cm, length 3cm, width 7cm b. height 2yd, length 8.5yd, width 3.4yd[br]2. Find the surface area of each Rectangular Pyramid to the nearest square unit.[br]a. slant height 8in, length 7in, width 3in b. slant height 3ft, length 9ft, width 5ft[br]3. Find the missing dimesion. Round to the nearest unit.[br]a. Rectangular Pyramid: volume 132cu ft, height ___, length 8ft, width 4ft[br]b. Rectangular Pyramid: volume 268cu ft, height 9ft, length ___, width 8ft[br]c. Rectangular Pyramid: surface area 135sq in, slant height 8.5in, length 5in, width ___[br]d. Rectangular Pyramid: surface area 221sq in, slant height 9in, length___, width 6.7in [br]4. How is the formula for volume of a prism like the formula for volume of a pyramid? How are the formulas different?
