Answer:
The surface are of a box = 1186.92 mm²
Step-by-step explanation:
Given in question as :
Diameter of cylinder = 18 mm
The height of cylinder = 12 mm
The surface area of cylinder = ( 2×
×r×h) + (2××r²)
where R is the radius , R = 
= 
Or Radius r = 9 mm
Or, The surface area of cylinder= ( 2××9×12) + 2××(9)²)
Or , The surface area of cylinder=(678.24) + (508.68)
Or ,The surface area of cylinder= 1186.92 mm²
Hence the surface are of a box = 1186.92 mm² Answer
Y=2x2−8x+5 is standard form

Answer:
45x + 180 = - 720
Step-by-step explanation:
Let the required number be x.
Therefore, product of 45 and x = 45x
180 added to 45x = 45x + 180
Since, 180 Added to the product of 45 and a number totals negative 720.
So, 45x + 180 = - 720
