A manufacturer uses a mold to make a part in the shape of a triangular prism. The dimensions of the part are shown below.

Question

Dimensions - a-14.4 mm
b-8.25 mm
c-7.5 mm
h-2.1 mm
Which estimate is closest to the volume in cubic millimeters in the part?
A)625
B)125***
C)249
D)446

Answer 1

the base has area
√(s(s-a)(s-b)(s-c)) where s = (a+b+c)/2
so the area of the base is
√(15.075(15.075-14.4)(15.075-8.25)(15.075-7.5)) = 22.936

so the volume is 22.936*2.1 = 48.1656

I suspect a typo somewhere. Or I misinterpreted the description.

Answer 2

The first choice is 65
