A shoe box in the shape of a rectangular prism measures 12in by 7in by 4in. What is the surface area of the shoe box?

320 sq in

Step-by-step explanation:

SA(rect prism) = 2(lw)+2(wh)+2(lh)

= 2(12·7)+2(7·4)+2(12·4)

= 2(84)+2(28)+2(48)

= 168+56+96

= 320

(sin 42)/31. = sinx)/37

sinx = 37 (sin42)/31

= 37× 0.66/31 = 0.787

x= 51.9

other angle opposite to y = 180-51.9-42

= 180- 93.9 =86.1

so

sin42)/31 = sin 86.1)/y

0.021 = 0.997 /y

y= 0.997/0.021 =47.47

an

y = 6x -3y -12

y +3y +12 = 6x

=> . x = { 2y / 3 +2 } this is equation of line in terms of x

=> . if line meets the x-axis the co-ordinates of meeting point would be ( x , 0 )

=> . x = 2 ( 0 ) / 3 + 2

=> . x = 2

so, the point is ( 2 , 0 )
