The Longstocking Toy Company is coming up with a new summer toy - Tinker the Tinman. The Tinmen are shipped out to local manufacturing plants in parts: the head,
the torso, and the limbs. However, they've been having a hard time finding the
correct packing material for the heads (see diagram below).
1) Identify the shapes used to create Tinker's head (face and hat) (be specific):
2) What is the volume of Tinker's head (the face and the hat)?

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.

faster, im not sure why but i know it is faster
