Perpendicular 35183

Calculate the surface and volume of a vertical prism if its height h = 18 cm and if the base is an equilateral triangle with side length a = 7.5 cm.

Correct answer:

S =  453.7139 cm2
V =  438.4254 cm3

Step-by-step explanation:

a=7.5 cm  h=18 cm  S1=43 a2=43 7.5224.357 cm2 o=3 a=3 7.5=245=22.5 cm  S=2 S1+o h=2 24.357+22.5 18=453.7139 cm2
V=S1 h=24.357 18=438.4254 cm3
