Equilateral 82576

Calculate the volume and surface area of a 9.6 cm high prism with a base of an equilateral triangle of length 4.8 cm.

Correct answer:

V =  95.7755 cm3
S =  158.1932 cm2

Step-by-step explanation:

a=4.8 cm h=9.6 cm  P=43 a2=43 4.829.9766 cm2  V=P h=9.9766 9.6=95.7755 cm3
S=2 P+3 a h=2 9.9766+3 4.8 9.6=158.1932 cm2
