Volume of Pyramids Formula
Ever wonder how to calculate the space inside a pyramid? The volume of any pyramid can be found using the formula V = ⅓Bh, where B is the area of the base and h is the height of the pyramid.
For rectangular pyramids, first find the base area using B = L × W. Then multiply by the height and divide by 3. For example, a rectangular pyramid with a 13 cm × 6 cm base and 14 cm height has a base area of 78 cm² and a volume of 364 cm³.
Square pyramids follow the same formula, but the base area is B = s² where s is the side length. A square pyramid with a 22 m × 22 m base and 35 m height has a base area of 484 m² and a volume of 5,646.6 m³.
💡 Remember that the height of a pyramid is always measured perpendicular to the base, not along the slant!
Working with these formulas becomes easier with practice. Try calculating the volume of a rectangular pyramid with base dimensions 17 ft × 32 ft and height 24 ft (answer: 4,352 ft³) or a square pyramid with 15 in sides and 19 in height (answer: 1,425 in³).

Triangular Pyramids
Triangular pyramids have triangular bases instead of rectangular or square ones. To find the base area, use the formula B = ½bh where b is the base of the triangle and h is the height of the triangle.
For example, a triangular pyramid with a base triangle measuring 13 units × 8 units and a pyramid height of 17 units has a base area of 52 square units. Applying our volume formula V = ⅓Bh, we get V = ⅓(52)(17) = 294.67 cubic units.
Practice problems show how versatile this formula is. A triangular pyramid with base dimensions of 16 ft × 5 ft and height 10 ft has a volume of 133.3 ft³. Another pyramid with a triangular base of area 112.5 yd² and height 20 yd has a volume of 750 yd³.
🔑 The key to solving any pyramid volume problem is finding the base area first, then applying the ⅓Bh formula!
When facing practice problems, first identify what you're looking for. For example, if given that a pyramid has a height of 5 inches and volume of 60 cubic inches, you can work backward to determine possible base shapes by using the formula V = ⅓Bh to find that the base area must be 36 square inches.

Pyramid Volume Applications
Understanding pyramid volumes helps you solve more complex problems. For example, when asked which solids have a volume of 40 cubic units, you'll need to apply different volume formulas for each shape and compare results.
When working with specific measurements, use the formula to find missing values. If a square pyramid has a volume of 50 cubic units and a base with sides of length 5 units (area = 25 square units), you can find the height by rearranging the formula: h = 3V/B = 3(50)/25 = 6 units.
Comparing different solids helps understand relationships between shapes. A cone and cylinder with the same radius and height have a volume ratio of 1:3. This means if a cone has volume 100π cubic feet, the cylinder would have 300π cubic feet.
👉 When identifying 3D shapes, focus on the number and types of faces. A triangular prism has 2 triangular faces and 3 rectangular faces.
Being able to visualize 3D shapes from their components is a valuable skill. For example, a solid constructed from 2 congruent triangles and 3 rectangles would be a triangular prism, not a pyramid (which would have a polygon base and triangular lateral faces).
