Question

I need help to find the surface area of the candle

Answer 1

Answer:

The surface area of the candle is $7.7\ in^{2}$

Step-by-step explanation:

we know that

The surface area of the candle is equal to the area of its triangular base plus the area of its three lateral triangular faces

so

$SA=\frac{1}{2}(2)(1.7)+3[\frac{1}{2}(2)(2)]=7.7\ in^{2}$
