Step-by-step explanation:

Given:

Sum of all sides = 110.4 cm

Find:

Surface area of cube

Computation:

Perimeter of cube = 12 x side

12 x side = 110.4

Side = 110.4 / 12

Side = 9.2 cm

Surface area of cube = 6 x Side²

Surface area of cube = 6 x 9.2²

Surface area of cube = 6 x 84.64

Surface area of cube = 504.84 cm²

Solve for x in the equation x2-12x+36 = 90-

Akimi4 [234]

Answer:

5.4

Step-by-step explanation:

x2-12x+36 = 90

=> 2x - 12x + 36 = *90

=> 2x - 12x = 90 - 36

=> -10x = 54

=> (-10x)/-10 = (54)/-10

=> x = 5.4
