A and B are similar cuboids. surface area of A: surface area of B = 25 : 36
Work out volume of A: volume of B
A 5:6
B 125 : 216
C 25 : 36
D 625 : 1296

Step-by-step explanation:

Surface area of cuboid A with side a is:

Same for cuboid B with side b:

Ratio of surface areas:

Volumes of A and B are:

And their ratio is:

Correct option is B

i belive those are the ones that are under 90 degreese.

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.
