Answer:

Correct answer:  V = 55.36 cm³

Step-by-step explanation:

Given:

a = 4 cm  edge of the bases

H = 8 cm  the height of the prism

Area of the base is equilateral triangle which area is:

B = a² · √3 / 4 = 4² · 1.73 / 4 = 16 · 1.73 / 4 = 6.92 cm²

Volume of the prism is:

V = B · H = 6.92 · 8 = 55.36 cm³

V = 55.36 cm³

God is with you!!!

Answer:

Step-by-step explanation:

height=√(4^2-2^2)=√(16-4)=√12=2√3

area of base=1/2×base×height=1/2×4×2√3=4√3

volume of prism=base area×height=4√3×8=32√3 cm³
