Many objects such as packing containers, buildings and components of machines have geometric representations that use two- and three-dimensional shapes. This leads to many practical scenarios that ...

The volume of a 3D shape is the amount of space inside it. Volume is measured in cubic units such as cm³ and m³. The volume, or capacity, of liquids is measured in millilitres or litres. The surface ...

Calculating the surface area of a rectangle is a fundamental skill that is frequently used in mathematics, as well as in many real-life scenarios. It’s a straightforward formula that measures the ...

The net of a 3D shape is what a shape looks like when opened into a 2D shape. The net can help to show the areas of each face that make up the surface area of a shape. The same units are needed for ...

A rectangular prism, also known as a cuboid, is a three-dimensional geometrical shape with six flat sides. These sides are all rectangles and can have different lengths, widths, and heights. The ...
