Answer: 18,27,36
Step-by-step explanation: We have to add all the ratios to get 9 and then divide 81 by 9 and get 9. The multiple 2, 3 and 4 by 9 getting 18, 27 and 36 respectively.
Surface are just means that you need to find the area of every face, then add.
TO find the Area of the rectangle do 16*8 = 128
For the triangle the area formula is b*h*1/2 So do 7*8*1/2= 28
There are four sides total and two triangles and two rectangles so 28+28+128+128= 312
SO the surface area is 312 in cubed
Move constant over (5x=38+2), combine terms (5x=40), divide both sides by 5 (x=8)
