Question

I need help to find the surface area of the candle

Answer 1

The surface area of the candle is
`7.7\ in^(2)`

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=(1)/(2)(2)(1.7)+3[(1)/(2)(2)(2)]=7.7\ in^(2)`
