Box a has a volume of 64 cubic meters. box b is similar to box a. to create box b, box a's dimensions were divided by 2. what is the volume of box b?
128 m3
8 m3
32 m3
16 m3

answer: 8 m^3

step-by-step explanation: v = a^3

a^3 = 64

a = 4 m

the box b has a = 2 m.

so, the volume is 2x2x2 = 8 m^3.

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.
