Answer:

volume of gold: 40.5 in³

Step-by-step explanation:


\sf Volume \ of \ trapezoid: area \ of \ base \ * \ length

Here the area of base:


\sf (1)/(2) *(base \ 1 + base \ 2 ) * height


\sf (1)/(2) *(3.2 + 2.2) * 1.5


\sf (1)/(2) *(5.4) * 1.5


\sf 4.05

Volume:

area of base * length

4.05 * 10

40.5 in³
