You use cubic units when you describe volume because a cube is measuring 1 unit on each edge and the edge has a volume of one cubic unit.
Describing the volume or capacity of spaces or containers.
You could use cubic yards or cubic meters.
cubic units
Volume is typically measured in cubic units. Common units include cubic centimeters (cm³), cubic meters (m³), liters (L), and milliliters (mL). In the imperial system, volume is often measured in cubic inches, cubic feet, and gallons. The choice of units depends on the context and the size of the object being measured.
The answer depends on the scale but commonly used units are cubic centimetres, cubic metres, cubic kilometres.
You would use the cubic meter (m^3) to express the volume of a textbook in SI units.
There is no standard unit of spherical volume. One would use the same units for describing the volume of any body, i.e. cubic-feet, cubic-meters, cubic-whatever. When one measures a space or object's volume these are the units used with the "cubic" coming from measuring the three dimensions an object takes up in space; length, width and depth. All three measurements must be in the same units; 1ft x 1ft x 1ft = 1 cubic-foot. You'll need the following equation for spherical volume: V= 4/3 x pi x r3 where "r" is the radius of the sphere.
Volume is typically measured in liters (L) or cubic meters (m^3) for larger quantities, and milliliters (mL) or cubic centimeters (cm^3) for smaller amounts. Other common units for volume include gallons, fluid ounces, and cubic feet.
The volume of a solid is measured in cubic units
You can use any measurement but only if your adding cubic to it
The SI unit for volume is the cubic meter (m³). Other common units include liters (L) and milliliters (mL).
Cubic meters or cubic feet would be appropriate units of measure to find the volume of a hollow block with an inner cavity.
