Explanation:

Step1: Calculate triangle perimeter

Add all side lengths: $3 + 4 + 5$

Step2: Calculate triangle area

Use right triangle area formula: $\frac{1}{2} \times 3 \times 4$

Step3: Calculate pyramid volume

Assume it's a right pyramid with base area equal to the triangle area, height = 5m (matching the triangle's hypotenuse, a logical extension here). Use volume formula: $\frac{1}{3} \times \text{base area} \times 5$

Answer:

Perimeter: $12$ m
Area: $6$ m²
Volume: $10$ m³
