7. Use formulas to find the surface area of the prism below (drawing not to scale). 20 cm
14.1 cm
10 cm
10 cm

surface area =782

Step-by-step explanation:

start with finding the area of all the rectangular faces and adding them together.

-face 1: 20*10=200

-face 2: 20*14.1=282

-face 3: 20*10=200

add them all together--200+282+200=682

next find the area of the two triangular bases

-base 1: 1/2bh=(1/2)(10)(10)=(1/2)(100)=50

-base 2: 1/2bh=(1/2)(10)(10)=(1/2)(100)=50

add those two areas together--50+50=100

finally, add the combined areas of the the rectangular faces and the two triagular bases together to get the total surface area of the triangular prism--

--100+682=782

that means 782 is the total surface area of the triangular prism.

the answer is b. 60. each interior angle in 120, so the exterior angle must be 60 in order to add up to 180

step-by-step explanation:
