The image you provided is a reference chart showing different types of pyramids and their volume formulas. Since no specific problem was asked, I’ll assume you want to understand how to use this chart — for example, to calculate the volume of one of these pyramids if given dimensions.
Let’s pick one as an example:
Square Pyramid
From the chart:
- Volume = (1/3) × B × h
- Also written as V = (1/3) × a² × h (since base area B = a² for a square)
Suppose we are told:
→ Base side length (a) = 6 cm
→ Height (h) = 9 cm
Step-by-step calculation:
1. Find base area:
B = a² = 6 × 6 = 36 cm²
2. Plug into formula:
V = (1/3) × 36 × 9
3. Multiply 36 × 9 first:
36 × 9 = 324
4. Then divide by 3:
324 ÷ 3 = 108
So, volume = 108 cm³
✔ Double-check:
(1/3) × 36 × 9 = 12 × 9 = 108 → Correct!
You can do the same for any pyramid type using its formula from the chart.
Final Answer:
For a square pyramid with base side 6 cm and height 9 cm, the volume is 108 cm³.
