The surface area of a triangular pyramid is 408 m2.

if all the faces of the pyramid are congruent, what is the area of one face of this pyramid?

a.
51 m2

b.
136 m2

c.
68 m2

d.
102 m2

D.

Step-by-step explanation:

Given : The surface area of a triangular pyramid is .

We know that the total number faces in a triangular pyramid =4

If all the faces of the pyramid are congruent, then the area of one face of this pyramid will be :_

Hence, the area of one face of this pyramid =

i think it is c, not positive though

step-by-step explanation:

answer:

step-by-step explanation:

here, the total dishes = 10

dishes having meat = 3 ( chicken, meatloaf and hamburger )

thus, the probability of having meat on the chosen dishes = number of dishes having meat / total dishes

=

therefore, the probability of not having meat = 1- the probability of having meat on the chosen dishes

=

=

=

⇒ option b is correct.
