What is the surface area of this square pyramid

28

Step-by-step explanation:

33 square feet

Step-by-step explanation:

Surface area is the sum of the areas of all of the faces.

Area of the triangle:

4*3/2= 6

Since there are four triangles, we need to multiply that by four.

6*4=24

Area of the base (the square):

3*3=9

Now we need to add those together.

24+9=33

Thus, the surface area is 33 square feet.

a. turk and mcalister

b. howard, mission, and market

c. yes. since streets end some do not cross yet are not parallel to others. example: mcalister and 5th

step-by-step explanation:

parallel lines are lines which do not intersect ever and look a lot like railroad tracks. turk, mcalister and golden gate are examples of these.

intersect are streets which cross each other and a car on one can reach the other. howard, mission, and market intersect with 6th.

skew lines are lines which neither intersect nor are parallel. these lines exist here because some streets end and never intersect another like mcalister and 5th.

the answer is simply just 6n add the two together as they have an n
