Answer:
180m²
Step-by-step explanation:
In order to solve this question, we have to find the area of the pyramid with a pentagonal base.
This pyramid has slant height = 24m
Since the base is a pentagon, it means it is 5 sided.
Each side of the base = 3m
The area of the pyramid = 1/2 × 5(side length) × slant height
= 1/2 × 5(3) × 24
= 180m²
Therefore, the square meters of metal needed to cover the faces of the pyramid = 180m²
