Acube has edge length 6 in. if the edge length of the cube is doubled, what happens to the surface area?
a: the surface area is doubled.
b: the surface area is multiplied by 4.
c: the surface area is multiplied by 1/4.
d: the surface area is halved.

answer: 32.68

step-by-step explanation:

x=2

i believe the answer is d.

hope it you! : d

0 is its x and y coordinate

the largest number of the four options is 1.8 x 10-2

you have it in scientific notation.

1.80 x 10-6   = 0.00000180

1.80 x 10-4   = 0.000180 (bigger, or "less small", than the former one)

so

1.8 x 10-2       = 0.0180. as you see. the "less small", or the biggest one of them all.

as you have negative exponent, it means you are dividing 1.8 by 100 (i.e. moving the dot towards left, two times).

if you had positive exponent for the scientific notation, power of tenths, you would be multiplying times 100 (moving the dot towards right) as below:

1.8 x (10)2 = 180

so. if you have negative exponent in scientific notation, move the dot toward left. if it is positive, toward right as many times the exponent tells you.
