Remember, equilateral means that all the sides are equal. 
SA = (ph) + 2B
P = perimeter of base
H = height
B = area of base

Thank you!

Yep!

To find the perimeter would I just multiply 2.8x2 and 1.5x2?

hlambach · Answer

Perimeter is all the sides added together

What if the problem is only giving me the base (2.8) and height (1.5) of the prism though?

hlambach · Answer

That's enough. Remember, it is an equilateral triangle, meaning the measure of the sides of the triangle are all the same.
