The regular

The regular triangular prism has a base in the shape of an isosceles triangle with a base of 86 mm and 6.4 cm arms; the height of the prism is 24 cm. Calculate its volume.

Correct answer:

V =  489.1941 cm3

Step-by-step explanation:

a=86 mm cm=86:10  cm=8.6 cm r=6.4 cm h=24 cm  h1=r2(a/2)2=6.42(8.6/2)24.7403 cm  S1=2h1 a=24.7403 8.620.3831 cm2  V=S1 h=20.3831 24=489.1941 cm3
