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!!!
What's right? i dont see any thing
Use cosine rule:-
b^2 = 41^2 + 20^2 - 2*20*41*cos 36
= 754.21
b = 27.5
you can now find angle A using the sine rule
27.5 / sin 36 = 41 / sin A
sin A = 0.87633
< A = 61.2 degrees
