Question

What is the surface area of an equilateral trianglular prism with bases that have an area of 15mm^2 and three rectangular faces that each have an are of 20mm^2

Answer 1

Answer:

Therefore, we conclude that  the surface area of an equilateral triangular prism is 90mm^2.

Step-by-step explanation:

We have the equilateral triangular prism with bases that have an area of 15mm^2 and three rectangular faces that each have an are of 20mm^2.  

We calculate  the surface area of an equilateral triangular prism.

We get :

$S=2\cdot 15+3\cdot 20=30+60=90$

Therefore, we conclude that  the surface area of an equilateral triangular prism is 90mm^2.
