Ignore the blue thing btw Marie made a model (shown below) of the square pyramid she plans to build when she grows up.
8 m
12 m
12 m
Find the surface area of the model.
m2

336m^2

Explanation:

The pyramid can be seen as four identical triangles and a square (the base)

Area of four triangles: 1/2 x 12 x 8 x 4 = 192m^2

Area of square: 12 x 12 = 144m^2

Area of pyramid: 144 + 192 = 336m^2

It's 336 (I did it on khan and it worked)

Step-by-step explanation:

44

step-by-step explanation:

$4034.40

the perimeter of the field is the sum of the lengths of the four sides:

47 yd + 158 yd + 47 yd + 158 yd = 410 yd

the cost of 3 ft (1 yd) of fence is 3×$3.28 = $9.84.

so the cost of jake's wood perimeter fance is

(410 yd) × ($9.84 /yd) = $4034.40
