The volume of a three-dimensional shape is a measurement of the space occupied by the shape.
Volume is measured in cubic units.
The volume of a unit cube
= 1 unit × 1 unit × 1 unit
= 1 unit3 ( Read as one cubic unit )
The volume of a cube with sides 1 cm × 1 cm × 1 cm
Volume = 1 cm × 1 cm × 1 cm = 1 cm3 ( Read as one cubic cm )
Some important units of conversion for volume are:
1 cm3 = 1,000 mm3
1 m3 = 1,000, 000 cm3
A cube is a three-dimensional figure with equal edges and six matching square sides.
The figure above shows a cube. The dotted lines indicate edges hidden from your view.
If s is the length of one of its sides, then the volume of the cube is s × s × s
Volume of the cube = s3
Since the cube has six square-shape sides, the
Surface area of a cube = 6s2Worksheet to calculate volume and surface area of cubes.
Imagine making cuts along some edges of a cube and opening it up to form a plane figure. The plane figure is called the net of the cube. There are 11 possible nets for a cube as shown in the following figures.
