The volume of a cuboid is found by multiplying its length, width, and height.
Formula: Volume of a Cuboid = Length × Width × Height
Example: Imagine a rectangular fish tank with a length of 50cm, a width of 30cm, and a height of 40cm. What's the volume of water it can hold?
Volume = 50cm × 30cm × 40cm = 60,000 cubic centimeters (cm³)
Real-World Application: Knowing the volume helps you determine how many fish you can safely keep in the tank!
A cylinder is a 3D shape with two parallel circular bases connected by a curved surface. Think of a can of Milo, a water bottle, or even the iconic Supertrees at Gardens by the Bay (okay, maybe not *exactly* a cylinder, but close enough!).
Formula: Volume of a Cylinder = π × Radius² × Height

Where π (pi) is approximately 3.142
Example: Let's say you have a cylindrical container with a radius of 7cm and a height of 15cm. What's its volume?
Volume = 3.142 × (7cm)² × 15cm = 2310.93 cm³ (approximately)
Real-World Application: This helps determine how much liquid a container can hold, useful for baking or even industrial applications.
Let's look at some examples that are relevant to Singaporean students:
Interesting Fact: The Gardens by the Bay Supertrees incorporate sustainable technology, mimicking the ecological function of real trees!
Here are some tips to help your child excel in mensuration questions:
Singlish Tip: Don't be "kayu" (wooden) during the exam! Stay calm and apply what you've learned. Confirm plus chop, you can do it!
By understanding the concepts and practicing regularly, your child can confidently tackle volume calculations in the singapore secondary 4 E-math syllabus. Good luck to your child! Jiayou!
Before diving into triangular and trapezoidal prisms, let's solidify the fundamental concept of a prism. A prism is a three-dimensional solid with two identical ends (bases) and flat rectangular sides. The volume of any prism is found by multiplying the area of its base by its height. This simple formula, Volume = Base Area × Height, is the key to unlocking volume calculations, regardless of the shape of the base. Understanding this foundational principle is crucial for success in your Singapore secondary 4 E-Math syllabus.
A triangular prism, as the name suggests, has a triangle as its base. To find its volume, first calculate the area of the triangular base using the formula: Area = ½ × base × height (of the triangle). Then, multiply this area by the height of the prism (the distance between the two triangular faces). Remember, the height of the triangle and the height of the prism are different measurements! Practice identifying these measurements correctly to avoid common errors in your singapore secondary 4 E-math exams.
Trapezoidal prisms feature a trapezoid as their base. Calculating the area of a trapezoid requires a slightly different approach. The formula for the area of a trapezoid is: Area = ½ × (sum of parallel sides) × height (of the trapezoid). Once you've determined the area of the trapezoidal base, multiply it by the height of the prism to find the volume. Many students find this trickier, so focus extra practice on trapezoidal prisms in your E-Math revision.
One frequent error is confusing the height of the base with the height of the prism. Always double-check which dimension you're using in your calculations. Another common mistake is using the wrong formula for the area of the base. Ensure you're using the correct formula for triangles and trapezoids. In the Lion City's dynamic education environment, where pupils deal with intense demands to succeed in math from elementary to tertiary tiers, locating a learning facility that combines knowledge with genuine passion can create significant changes in cultivating a appreciation for the subject.

A pyramid is a polyhedron formed by connecting a polygonal base and a point, called the apex. The volume of a pyramid depends on the area of its base and its height. Here's the formula:
Volume of a Pyramid = (1/3) * Base Area * Height
Let's say we have a square pyramid with a base side of 5 cm and a height of 9 cm. To find its volume:
Therefore, the volume of the square pyramid is 75 cm³.
A cone is a three-dimensional geometric shape that tapers smoothly from a flat base (usually circular) to a point called the apex or vertex. The volume of a cone is related to the volume of a cylinder with the same base and height. The formula is:
Volume of a Cone = (1/3) * π * r² * h
Where:
Imagine a cone with a radius of 4 cm and a height of 12 cm. Let's calculate its volume:
Therefore, the volume of the cone is approximately 201.06 cm³.
Interesting Fact: The formula for the volume of a cone is directly related to the volume of a cylinder. A cone's volume is exactly one-third of a cylinder's volume if they share the same base radius and height.
Let's consider a simplified model of the Merlion statue, a famous Singaporean landmark. Suppose the Merlion's body can be approximated as a cone with a base radius of 1.5 meters and a height of 8 meters. What is the approximate volume of this conical section?
Therefore, the approximate volume of the Merlion's cone-shaped body is 18.85 m³.

A sphere is a perfectly round geometrical object in three-dimensional space, like a basketball or a globe. The key measurement for a sphere is its radius (r), which is the distance from the center of the sphere to any point on its surface.
The formula for the volume (V) of a sphere is:
V = (4/3) * π * r³
Where π (pi) is approximately 3.142.
A hemisphere is simply half of a sphere, like a bowl or the dome of some buildings. To calculate its volume, you just halve the sphere's volume.
The formula for the volume (V) of a hemisphere is:
V = (2/3) * π * r³
Interesting Fact: The geodesic domes at Gardens by the Bay in Singapore are based on hemispherical geometry, showcasing real-world applications of these shapes!
Let's say the dome of the Singapore National Stadium can be approximated as a hemisphere with a radius of 160 meters. What is the volume of space enclosed by the dome?
Using the formula for the volume of a hemisphere:
V = (2/3) * π * r³
V = (2/3) * 3.142 * (160)³
V ≈ 8,579,461 cubic meters
Therefore, the volume of space enclosed by the dome of the National Stadium is approximately 8,579,461 cubic meters.
History: The Greek mathematician Archimedes is credited with deriving the formulas for the surface area and volume of a sphere. He was so proud of this discovery that he requested a sphere inscribed in a cylinder to be engraved on his tombstone!
