A right prism has a base that is an equilateral triangle. The height of the prism is equal to the height of the base. If the volume of the prism is 81, what are the lengths of the sides of the base?

Length of side of base is 5.45

Step-by-step explanation:

Here, since the base is an equilateral triangle and it is given that height of the prism is equal to that of the base, measures of base and height are equal.

⇒ Volume = 1/2 × b × h × h (b and h are equal)

⇒ 81 = 1/2 × b³

⇒ b³ = 162

⇒ b = ∛162 = 5.45

the answer is b.)

< 1=< 2

the answer for this question is : 360°

step-by-step explanation:

we have been given a triangle   we need to tell which one of these is a triangle below to map onto itself.

360° rotation is the complete rotation which eventually leads to the same figure which is given.

the correct will be, that is 360° that will cause the triangle below to map onto itself.
