Will mark Brainli if you give me an explanation

D

Step-by-step explanation:

To calculate the surface area of something, calculate the area of each side of the shape and add those values together.

In this problem, you have two sides equaling 10x10 which equals 200 in^2, two sides equaling 48 in^2 ( the triangles ), and two sides equaling 160 in^2 (the base 16x10).

I hope this helps!

answer: ff

f

step-by-step explanation: f

ff

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.
