Volume measures the space occupied by a three-dimensional solid. Volume is measured in cubic units like m³, cm³, in³. 1 liter equals 1000 cubic centimeters or 0.001 cubic meters
Scuba diving uses independent breathing equipment for underwater exploration. Christian J. Lambertsen coined the term "SCUBA" in 1952. Open-circuit systems discharge exhaled gas directly into water. Closed-circuit rebreathers recycle exhaled gases for longer dives
Cylinder is a three-dimensional solid with one curved surface and two circular bases. Bases are parallel and identical, forming a prism-like shape. No vertices exist as it has no corners
Volume measures three-dimensional space occupied by a shape. Common units include cubic centimeters, meters, inches, and feet. Volume formula: length x width x height for most shapes
Hollow cylinder has mass distributed between inner and outer surfaces. Cylinder is divided into infinite thin concentric rings. Each ring has mass dm and moment of inertia dI
Cylinder is a three-dimensional shape with two circular ends and one curved surface. Has two circular faces, no vertices, and two edges. First introduced in 1st grade geometry
