Cube
Pyramid
Cylinder

If a cube has a side length of 5 cm, calculate its total surface area.
Total surface area = 6 x (side length)² = 6 x (5 cm)² = 150 cm²
A cylinder has a radius of 3 cm and a height of 8 cm. Find its lateral surface area.
Lateral surface area
= 2 x π x radius x height
= 2 x π x 3 cm x 8 cm
= 48π cm² (approximately 150.8 cm²)
Calculate the volume of a sphere with a radius of 4 cm (use π ≈ 3.14).
Volume of sphere
= (4/3) x π x radius³
= (4/3) x π x (4 cm)³
= (4/3) x 3.14 x 64 cm³
≈ 267.95 cm³
Find the total number of edges in a triangular prism that has edges of length 6 cm, 8 cm, and 10 cm.
A triangular prism has 9 edges regardless of edge lengths.
