Write and simplify an expression for the surface area of a square pyramid with a base edge length of s in. & triangular faces with a height of 7 in. What is the surface area if the base edge length is 2.5 in.?

Step-by-step explanation:

-Let s be the base lengths and h be the slant heights of the trinagles.

-Surface area of the pyramid is the sum of the areas of all of it's face and can be given as:

#We substitute the length and height dimensions in our simplified formula to calculate the Surface area as:

Hence, the pyramid's surface area is

the ratio of white tiles to blue tiles is 48: 16. the ratio in it's simplest form is 3: 1.

step-by-step explanation:

ratio: take the first number and add a colon next to it, then add the second number after that. make sure the ratio order matches up with the written problem!

simplest form: we can simplify the ratio 48 : 16 by dividing both terms by the greatest common factor (gcf).

the gcf of 48 and 16 is 16.

divide both terms by 16:

48 ÷ 16 = 3

16 ÷ 16 = 1

reducing to simplest form:

48 : 16 = 3 : 1

36/60

36/2=18

60/2=30

18/30

18/3=6

30/3=10

6/10

6/2=3

10/2=5

your final answer would be 3/5 of an

hope this !
