Jack makes the pendant from solid gold.
He uses this formula.
D
ZOOM +
V=TL
where V - volume of a triangular prism (cm³)
T= area of the triangular face (cm)
L = length of the prism (cm)
mass = density x volume
the density of gold is 19 grams per cm³
the cost of 1 gram of gold is £40
Jack sells the pendant for £382 more than the total cost of the gold needed to make
the pendant.
How much does Jack sell the pendant for?
