Two similar solids a and b are shown. (hexagonal prism). solid a has a volume of 60cm^3. solid b has a surface area of 140cm^2. work out the total surface area of solid a

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.

the answer is 13

step-by-step explanation:

5*5=25

12*12=144

25+144=169

169^2=13
