Find the total surface area of this square based
pyramid.
10ft
10 ft
[? ]ft?

300

Step-by-step explanation:

area of triangle=

= 50

4 sides of the triangle

4*50=200

area of square= l*w

10*10=100

area of square+area of triangles

200+100=300

_=300

answer: 1, 3 and 5 are correct

step-by-step explanation:

step-by-step explanation:

given that ab is divided into equal parts as

ac, cd, de, ef, fg, gh, hi, ib.

from this we find that f is the midpoint of ab.

so using mid point formula we find

f = (3,7)

similarly considering fb, we get

h = mid point of fb = ((6,6) and g, mid point of fh is

g = (9/2, 13/2)

i is mid point of hb

so i =(15/2,11/2)
