$$\large{ h = \sqrt{ \frac{ 4\;c^2 - b^2 }{4} } }$$
Symbol English Metric
$$\large{ h }$$ = height $$\large{ in }$$ $$\large{ mm }$$
$$\large{ a, b, c }$$ = edge $$\large{ in }$$ $$\large{ mm }$$ ## Surface area of a Isosceles Triangle Wedge formula

$$\large{ A_s = b\;l + 2\;l\;c + h\;b }$$
Symbol English Metric
$$\large{ A_s }$$ = surface area $$\large{ in^2 }$$ $$\large{ mm^2 }$$
$$\large{ a, b, c }$$ = edge $$\large{ in }$$ $$\large{ mm }$$
$$\large{ h }$$ = height $$\large{ in }$$ $$\large{ mm }$$
$$\large{ l }$$ = length $$\large{ in }$$ $$\large{ mm }$$ ## Volume of a Isosceles Triangle Wedge formula

$$\large{ V = \frac{l\;b\;h}{2} }$$
Symbol English Metric
$$\large{ V }$$ = volume $$\large{ in^2 }$$ $$\large{ mm^2 }$$
$$\large{ a, b, c }$$ = edge $$\large{ in }$$ $$\large{ mm }$$
$$\large{ h }$$ = height $$\large{ in }$$ $$\large{ mm }$$
