I think it's 144
multiply 12 by 4 because there are 4 walls then multiply 3 by the product of 12×4 and that should be your awnser
Surface area
break it down
bottom and top
bottom=5 rectangle
top=2 triangles+2rectangle
areas
area of recatngle=lw
area of traignle=1/2lw
so total is
SA=(8 times 2.8)+(2.8 times 4.8) +(2.8 times 4.8)+(4.8 times 8)+(4.8 times 8)+(5 times 2.8)+(5 times 2.8)+(1/2 times 3 times 8)+(1/2 times 3 times 8)
(I'm not going to do all the math, just the result)
SA=178.08 yd^2
split the figure into 2 parts
top and bottom
bottom=rectagular prism=lwh
top=triangle tingie, wait, if we take 1/2 of it and put it with the other, half, we get a rectangular prism with 1/2 base so
bottom=8 times 2.8 times 4.8=107.52
top=1/2 times 8 times 3 times 2.8=33.6
add them
107.52+33.6=141.12 yd^3

Answer:
7e+10 + 9e+8 + 6.7e+4 + 8.99 × 10 to the power of 2 + 1/3.
Step-by-step explanation:
Answer:
y=0
Step-by-step explanation:
So your m=-2 or -2/1. And you say that your y-intercept is the origin. The origin is the (0,0). Therefore your y intercept is 0.
