I don't get how to do this, when I solved for it I got 125...

Answer 1

Answer 2

Total surface = Lateral surface (AL) and Area of base (AB)

AB= area of square base
AL=4*area of each triangular slant face, each of which has a base of 10, and a height S calculated using Pythagoras Theorem:

where
S=sqrt(5^2+12^2)

Add up all the areas to get the total surface area, AT.
AT should match one of the choices provided.

Answer 3

S equals 13.

Answer 4

so What I would do would be,
4*10+13...

Answer 5

5 times.

Answer 6

no I would do,.. 1/2 (12)(10)

which equals 60.. and there are 5 faces....so im doing something wrong..

Answer 7

@study100

Answer 8

ok s= 13

and s is your surface height

so 1/2(13)(10)

Answer 9

Yes, (1/2)(13)(10) for one slant face.
