Select the correct answer. The surface area of a cube is 600 square inches. What is the area of one of its faces?

A 6 square inches

B. 36 square inches

C. 75 square inches

D. 100 square inches

D=100 square inches

Step-by-step explanation:

Area of a square=side^2

Area of a cube=6xside^2

let the side be a

6a^2=600

a^2=600/6

a^2=100

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.
