Question

a triangular pyramid has four faces h = b = 1. What is the pryimands surface area?(There's no image)(

Answer 1

Let's find the area of one face

`A=(bh)/(2)`

Where h = b = 1.

`A=(1\cdot1)/(2)=(1)/(2)`

Given that there are four faces, we have to multiply the area above by 4

`S=4\cdot(1)/(2)=2`

Hence, the answer is 2 square units.
