The dimension of cuboid = 8×4×2;

The total surface area of cuboid = 2(lw+wh+hl);

Here l - length, w- width, h-height;

Total surface are = 2 (8×4+4×2+2×8)

= 2 (32+8+16) = 56×2 = 112 cm²;

This cuboid is cut into cube of equal sides 1cm, Volume of cube = 1cm^3;

Volume of cuboid = 8×4×2 = 64cm³;

Total no. of cubes = 64/1 = 64;

Total surface area of cube = 6;

The ratio of surface are of original cuboid to unit cube = 112/6 = 56/3

2x² + x + 4 = 0

(Divide by 2 through)

x² + 1/2x + 2 = 0

(Subtract 2 from both sides)

x² + 1/2x = -2

(add (b/2)² to both sides)

x² + 1/2x + (1/4)² = -2 + (1/4)²

(Complete the square)

(x + 1/4)² = -31/16

(Square root both sides)

x + 1/4 = ±√(-31/16)

x + 1/4 = ±i√(31/16)

Subtract 1/4 from both sides:

x = i√(31/16) - 1/4 or - i√(31/16) - 1/4

=> Both roots are imaginary numbers

=> There is no real roots
.

If we draw the figure for given question we will see a right triangle AOP right angled at P. [It is to be noted that tangent and radius form an angle of 90° at the point of contact.] In ∆AOP Cos ( angle APO ) = AP/OA Cos 45° = 5/OA 1 = 5/OA OA = 5 cm Hence, the radius of the given circle is 5 cm.
